spi: spi-mem: Fix spi_mem_poll_status()
In spi_mem_exec_op(), in case cs_gpiod descriptor is set, exec_op()
callback can't be used.
The same must be applied in spi_mem_poll_status(), poll_status()
callback can't be used, we must use the legacy path using
read_poll_timeout().
Tested on STM32mp257c-ev1 specific evaluation board on which a
spi-nand was mounted instead of a spi-nor.
