The drmm_add_action_or_reset function automatically invokes the action
(sysfs removal) in the event of a failure; therefore, there's no
necessity to call it within the return check.

Modify the return type of xe_gt_ccs_mode_sysfs_init to int, allowing the
caller to pass errors up the call chain. Should sysfs creation or
drmm_add_action_or_reset fail, error propagation will prompt a driver
load abort.
