This patch releases semaphore locks when
an error occurrs while attempting to
download firmware for the bcm driver.
When downloading firmware for this driver,
a process is expected to call
the following ioctl's in this order:
(1)IOCTL_BCM_BUFFER_DOWNLOAD_START,
(2)IOCTL_BCM_BUFFER_DOWNLOAD, and (3)
IOCTL_BCM_BUFFER_DOWNLOAD_STOP.
Semaphore, “Adapter->fw_download_sema” is
expected to be acquired in the first ioctl,
IOCTL_BCM_BUFFER_DOWNLOAD_START, and it should
block until IOCTL_BCM_BUFFER_DOWNLOAD_STOP
is called. In this case, if an error
occurred before STOP finished, the semaphore
"Adapter->fw_download_sema" was not being released.
