ext4: only check dquot_initialize_needed() when debugging

commit dea9d8f7643fab07bf89a1155f1f94f37d096a5e upstream.

ext4_xattr_block_set() relies on its caller to call dquot_initialize()
on the inode.  To assure that this has happened there are WARN_ON
checks.  Unfortunately, this is subject to false positives if there is
an antagonist thread which is flipping the file system at high rates
between r/o and rw.  So only do the check if EXT4_XATTR_DEBUG is
enabled.
