bcache: use sysfs_match_string() instead of __sysfs_match_string()
The arrays (of strings) that are passed to __sysfs_match_string() are
static, so use sysfs_match_string() which does an implicit ARRAY_SIZE()
over these arrays.
Functionally, this doesn't change anything.
The change is more cosmetic.
It only shrinks the static arrays by 1 byte each.
