xfs: Add the missed xfs_perag_put() for xfs_ifree_cluster()

Browse Source 
xfs_ifree_cluster() calls xfs_perag_get() at the beginning, but forgets to
call xfs_perag_put() in one failed path.
Add the missed function call to fix it.

Fixes: ce92464c18 ("xfs: make xfs_trans_get_buf return an error code")
