gfs2: Fix error exit in do_xmote
Before this patch, if an error was detected from glock function go_sync by function do_xmote, it would return. But the function had temporarily unlocked the gl_lockref spin_lock, and it never re-locked it. When the caller of do_xmote tried to unlock it again, it was already unlocked, which resulted in a corrupted spin_lock value. This patch makes sure the gl_lockref spin_lock is re-locked after it is unlocked. Thanks to Wu Bo <wubo40@huawei.com> for reporting this problem.
