scsi: esas2r: Replace semaphore fm_api_semaphore with mutex
The semaphore 'fm_api_semaphore' is used as a simple mutex, so it should be written as one. Semaphores are going away in the future. Signed-off-by: Binoy Jayan <binoy.jayan@linaro.org> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
