spi: stm32-ospi: Fix NULL vs IS_ERR() bug in stm32_ospi_get_resources()

Browse Source 
This code was changed from using devm_ioremap() which returns NULL to
using devm_ioremap_resource() which returns error pointers.  Update
the error checking to match.

Fixes: defe01abfb ("spi: stm32-ospi: Use of_reserved_mem_region_to_resource() for "memory-region"")
