xfs: return corresponding errcode if xfs_initialize_perag() fail
In xfs_initialize_perag(), if kmem_zalloc(), xfs_buf_hash_init(), or
radix_tree_preload() failed, the returned value 'error' is not set
accordingly.
Reported-as-fixing: 8b26c5825e02 ("xfs: handle ENOMEM correctly during initialisation of perag structures")
Fixes: 9b2471797942 ("xfs: cache unlinked pointers in an rhashtable")
