[PATCH 2/3] mtd: rawnand: stm32_fmc2: Ensure to return error code

[Andrew Goodbody]

In stm32_fmc2_nfc_probe there are 3 error returns that do not set the
error code before returning which could lead to the error being silently
ignored. Just return -EINVAL in each case.

This issue was found by Smatch.
