[PATCH 5.4 CANDIDATE 09/17] xfs: simplify a check in xfs_ioctl_setattr_check_cowextsize

[Chandan Babu R <chandan.babu@oracle.com>]

From: Christoph Hellwig <hch@lst.de>

commit 5e28aafe708ba3e388f92a7148093319d3521c2f uptream.

Only v5 file systems can have the reflink feature, and those will
always use the large dinode format.  Remove the extra check for the
inode version.
