[PATCH v2] btrfs: remove -ERANGE check and avoid errno overriding in btrfs_get_acl()

[Chengguang Xu <cgxu519@gmx.com>]

Remove -ERANGE error check because there is no chance to get into
this condition and meanwhile avoid overriding errno to -EIO in
btrfs_get_acl().

Signed-off-by: Chengguang Xu <cgxu519@gmx.com>

v2:
- Avoid errno overriding instead of print error message in error case.
- Change commit log for better understanding.
