Nicolas Toromanoff bbf2cb1ea1 crypto: stm32/crc32 - Avoid lock if hardware is already used 
If STM32 CRC device is already in use, calculate CRC by software.

This will release CPU constraint for a concurrent access to the
hardware, and avoid masking irqs during the whole block processing.

Fixes: 7795c0baf5 ("crypto: stm32/crc32 - protect from concurrent accesses")
