Subject: [PATCH] Staging: bcm: Clean up patch that calls semaphore
 down_trylock directly.

This patch evaluates/calls the down_trylock locking
function directly, instead of storing the results
in a variable and evaluating the variable. These
changes were made in:
IOCTL_BCM_BUFFER_DOWNLOAD_STOP and
IOCTL_BCM_BUFFER_DOWNLOAD_START.
