md/md-bitmap: fix stats collection for external bitmaps
The bitmap_get_stats() function incorrectly returns -ENOENT for external
bitmaps.
Remove the external bitmap check as the statistics should be available
regardless of bitmap storage location.
Return -EINVAL only for invalid bitmap with no storage (neither in
superblock nor in external file).
Note: "bitmap_info.external" here refers to a bitmap stored in a separate
file (bitmap_file), not to external metadata.
Fixes: 8d28d0ddb986 ("md/md-bitmap: Synchronize bitmap_get_stats() with bitmap lifetime")
