[PATCH] staging: ath6kl: Including a header file to fix a compilation error

[Vipin Mehta]

The commit fixes a compilation error that was encountered while using a specific kernel configuration file. The problem was the use of some fuunctions defined in <linux/semaphore.h> without including the header file explicitly. It was probably working before because of the dependency getting implicitly satisfied via some other header file. Also, eliminating the inclusion of the same header file more than once. The code needs additional cleanup and may be addressed by a subsequent commit.
