UBIFS: fix oops on error path in read_pnode

BugLink: http://bugs.launchpad.net/bugs/761134

commit 54acbaaa523ca0bd284a18f67ad213c379679e86 upstream.

Thanks to coverity which spotted that UBIFS will oops if 'kmalloc()'
in 'read_pnode()' fails and we dereference a NULL 'pnode' pointer
when we 'goto out'.
