gfs2: Don't leave s_fs_info pointing to freed memory in init_sbd
commit 4c62bd9cea7bcf10292f7e4c57a2bca332942697 upstream.
When alloc_percpu() fails, sdp gets freed but sb->s_fs_info still points
to the same address. Move the assignment after that error check so that
s_fs_info can only point to a valid sdp or NULL, which is checked for
later in the error path, in gfs2_kill_super().
