[PATCH 1/4] crypto: omap-sham: Remove useless check for non-null request

ahash_request 'req' argument passed by the caller omap_sham_handle_queue() cannot be NULL here because it is obtained from non-NULL pointer via container_of(). This fixes smatch warning: drivers/crypto/omap-sham.c:812 omap_sham_prepare_request() warn: variable dereferenced before check 'req'
