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.
