ubifs: Call iput(xino) only once in ubifs_purge_xattrs()

An iput(xino) call was immediately used after a return value check
for a remove_xattr() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
