crypto: stm32/crc32 - fix run-time self test issue.
Fix wrong crc32 initialisation value:
"alg: shash: stm32_crc32 test failed (wrong result) on test vector 0,
cfg="init+update+final aligned buffer"
cra_name="crc32c" expects an init value of 0XFFFFFFFF,
cra_name="crc32" expects an init value of 0.
Fixes: b51dbe90912a ("crypto: stm32 - Support for STM32 CRC32 crypto module")
