This patch changes the behavior, to exit the loop when a NULL element is found and n == -1. Essentially, this aligns the behavior with the doc-string. There are currently many users of `match_string()`, and so, in order to go through them, the next patches in the series will focus on doing some cosmetic changes, which are aimed at grouping the users of `match_string()`.

There are a few parts to the intention here (with this change): 1. Align with sysfs_match_string()/__sysfs_match_string() 2. This helps to group users of `match_string()`: a. those that use ARRAY_SIZE(_a) to specify the number of elements b. those that use -1 to pass a NULL terminated array of strings c. special users, which (after eliminating 1 & 2) are not that many This change is done treewide. Updates to the new match_string() helper will be done on a per-subsystem basis, as the cadence of each subsystem differs.

After this change, work can start on migrating subsystems to use this new helper. Since the original helper is pretty used, migrating to this new one will take a while, and will be reviewed by each subsystem.
