mtd: spi-nor: spansion: make sure local struct does not contain garbage
Following errors were seen with um-x86_64-gcc12/um-allyesconfig:
+ /kisskb/src/drivers/mtd/spi-nor/spansion.c: error: 'op' is used uninitialized [-Werror=uninitialized]: => 495:27, 364:27
Initialise local struct spi_mem_op with all zeros at declaration in
order to avoid using garbage data for fields that are not explicitly
set afterwards.
