[PATCH i-g-t v4 2/5] lib/igt_sysfs: Rename debug level APIs/variables to debug mask

[Pranay Samala]

The debug log mask is a mask rather than level. Rename each level
occurance to mask.

v3:
- Refactored for readability and address logical comment.

v4:
- Rename debug_level parameter to mask (Kunal)

Fixes: 56b91193b825 ("lib/igt_sysfs: Implement dynamic adjustment of debug log level")
