Fix loganalyzer to ignore port attr errors with any exit code

[deerao02]

Description of PR

The existing ignore pattern only matched 'Failed to get port attr' errors with exit code -2. Other negative exit codes (e.g., -6) from syncd were still flagged as test failures. Generalize the pattern to match any negative exit code (-\d+).
The qos.test_qos_sai.TestQosSai.testParameter test consistently fails on teardown on Arista-7060X6-64PE-P32O64 (LT2 topology) because the loganalyzer catches syncd errors like:

ERR syncd#syncd: :- collectData: Failed to get port attr for VID 0x100000000000b, RID:0x100000055: -8

An ignore rule already exists in loganalyzer_common_ignore.txt but it only matches exit code -2. On this platform, syncd returns -8, causing 16 spurious matches per run and a 0% pass rate on LT2 topology across all OS versions (20251110.23 through 20251110.30).

Approach

What is the motivation for this PR?

The existing ignore pattern only matched 'Failed to get port attr' errors with exit code -2. Other negative exit codes (e.g., -6) from syncd were still flagged as test failures.

How did you do it?

Changed the regex in loganalyzer_common_ignore.txt from:

r, ".* ERR syncd\d*#syncd: :- collectData: Failed to get port attr for VID 0x[0-9a-fA-F]+, RID:0x[0-9a-fA-F]+: -2.*"

to:

r, ".* ERR syncd\d*#syncd: :- collectData: Failed to get port attr for VID 0x[0-9a-fA-F]+, RID:0x[0-9a-fA-F]+: -\d+.*"

This matches any negative return code from collectData, which is a benign platform-specific log message that does not indicate a real test failure.

How did you verify/test it?

Verified the updated regex matches the actual syslog lines from the failing test runs:
bash
echo 'ERR syncd#syncd: :- collectData: Failed to get port attr for VID 0x100000000000b, RID:0x100000055: -8' | grep -P 'collectData: Failed to get port attr for VID 0x[0-9a-fA-F]+, RID:0x[0-9a-fA-F]+: -\d+'

Any platform specific information?

Consistently reproduced on Arista-7060X6-64PE-P32O64 (Broadcom ASIC, LT2 topology). The  -8  return code appears specific to this hardware SKU.

Supported testbed topology if it's a new test case?
