mmc_test: initialize mmc_test_lock statically
The mutex mmc_test_lock is initialized at every time mmc_test device
is probed. Probing another mmc_test device may break the mutex, if
the probe function is called while the mutex is locked.
This patch fixes it by statically initializing mmc_test_lock.
