drivers: spi: stm32: replace an #if with an if() in transceive()

etienne-lms · kartben · commit 3b856ccb11ca · 2025-10-23T18:07:18.000+02:00
Replace a #ifndef directive with a if(!IS_ENABLED()) instrcution
in transceive() function. This change makes later integration of RTIO
support in this function smoother, polluting a bit less this function
with #if based directives.
