r269533, which was tested before r269457 was committed, implicitely relied on the Giant to protect the manipulations of the softdepmounts list. Use softdep global lock consistently to guarantee the list structure now. Insert the new struct mount_softdeps into the softdepmounts only after it is sufficiently initialized, to prevent softdep_speedup() from accessing bare memory. Similarly, remove struct mount_softdeps for the unmounted filesystem from the tailq before destroying structure rwlock.
