spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe()

Browse source

[ Upstream commit 888a0a802c ]

platform_get_resource_byname() can return NULL, which would cause a crash
when passed the pointer to resource_size().

Move the fiu->memory_size assignment after the error check for
devm_ioremap_resource() to prevent the potential NULL pointer dereference.
