staging: r8712u: Simplify semaphores
I am preparing to convert this driver from semaphore to mutex locking,
The first step has been to eliminate a number of semaphores that were
initialized but never used, and one whose only use was a single "up"
after initialization. A total of 9 semaphores were removed in this process.
One other change was to remove some inline semaphore routines that were
unused.
In addition, several cases had the following structure:
down()
if () {
...
}
up()
The locking overhead was reduced by moving the up/down inside the if
block.
