Linux Kernel Markers: fix marker mutex not taken upon module load

Linux Kernel Markers: fix marker mutex not taken upon module load

Upon module load, we must take the markers mutex.  It implies that the marker
mutex must be nested inside the module mutex.

It implies changing the nesting order : now the marker mutex nests inside the
module mutex.  Make the necessary changes to reverse the order in which the
mutexes are taken.

Includes some cleanup from Dave Hansen <haveblue@us.ibm.com>.
