Yun Zhou 3a00c9bc8e ext4: remove ea_inode_array mechanism in favor of ext4_put_ea_inode()
Now that ext4_put_ea_inode() handles deferred iput safely for all cases
(using iput_if_not_last + embedded llist_node), the ea_inode_array
mechanism for batching deferred iputs is redundant.

Remove:
- ext4_expand_inode_array() and ext4_xattr_inode_array_free()
- struct ext4_xattr_inode_array and EIA_INCR/EIA_MASK defines
- ea_inode_array parameter from ext4_xattr_inode_dec_ref_all(),
  ext4_xattr_release_block(), and ext4_xattr_delete_inode()
- ea_inode_array variable from ext4_evict_inode()

Instead, ext4_xattr_inode_dec_ref_all() now calls ext4_put_ea_inode()
directly after processing each EA inode.  This simplifies the code
by eliminating multi-layer parameter threading and removes the need
for callers to manage array lifetime.
