The icc_commit_set() function, used by the debugfs interface, checks
the validity of the global cur_path pointer using IS_ERR_OR_NULL().
However, in the specific case where cur_path is NULL, while
IS_ERR_OR_NULL(NULL) correctly evaluates to true, the subsequent call
to PTR_ERR(NULL) returns 0.
This causes the function to return a success code (0) instead of an
error, misleading the user into believing their bandwidth request was
successfully committed when, in fact, no operation was performed.
Fix this by adding an explicit check to return -EINVAL if cur_path is
NULL. This prevents silent failures and ensures that an invalid
operational sequence is immediately and clearly reported as an error.
