crypto: stm32/crc32 - fix parsing list of devices
smatch warnings:
drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn:
can 'crc' even be NULL?
Use list_first_entry_or_null instead of list_first_entry to retrieve
the first device registered.
The function list_first_entry always return a non NULL pointer even if
the list is empty. Hence checking if the pointer returned is NULL does
not tell if the list is empty or not.
