xfs: skip always_cow inodes in xfs_reflink_trim_around_shared
xfs_reflink_trim_around_shared tries to find shared blocks in the
refcount btree. Always_cow inodes don't have that tree, so don't
bother.
For the existing always_cow code this is a minor optimization. For
the upcoming zoned code that can do COW without the rtreflink code it
avoids triggering a NULL pointer dereference.
