exfat: keep FITRIM within the requested range
exfat_find_free_bitmap() searches the entire allocation bitmap and may
wrap around to its beginning. exfat_trim_fs() does not verify that the
returned cluster is still within the requested FITRIM range.
As a result, a partial FITRIM operation may discard free clusters outside
the user-specified range and report a trimmed length larger than the
requested length.
Validate each returned cluster against the requested range and stop the
search when it wraps around or passes the range end.
