Set drm debug log level for DP messages and DRIVER messages to fix
exceeding disk usage limit in modeset-transition test cases.
v2: -Rename DEBUG_LEVEL to DRM_DEBUG_LEVEL.
-Declared log level globally.
-Added check for checking default log level before update.
v3: -Close sysfs_fd.
v4: -Close sysfs_fd with close() call.
