Kenneth D. Merry a02e196edd Switch geom_disk over to using a pool mutex. 
The GEOM disk d_mtx is only acquired on disk creation and destruction.
It is a good candidate for replacement with a pool mutex.  This eliminates
the mutex initialization and teardown and the mutex and name variables
themselves from struct disk.

sys/geom/geom_disk.h:
	Take d_mtx and d_mtx_name out of struct disk.

sys/geom/geom_disk.c:
	Use mtx_pool_lock() and mtx_pool_unlock() to guard the disk
	initialization state instead of a dedicated mutex.

	This allows removing the initialization and destruction of
	d_mtx.

sys/sys/param.h:
	Bump __FreeBSD_version to 1100119 for the change to struct disk.
