[PATCH v2] mtd: rawnand: intel: check the mtd name only after setting the variable

[Martin Blumenstingl]

Move the check for mtd->name after the mtd variable has actually been
initialized.

While here, also drop the NULL assignment to the mtd variable as it's
overwritten later on anyways and the NULL value is never read.

Fixes: 0b1039f016e8a3 ("mtd: rawnand: Add NAND controller support on Intel LGM SoC")

changes since v1:
- don't drop the check but actually move it after the mtd variable has
  been initialized as suggested by Miquel Raynal
