mtd: rawnand: txx9ndfmc: Drop if block with always false condition

txx9ndfmc_remove() is only called after txx9ndfmc_probe() completed
successfully. In this case platform_set_drvdata() was called with a
non-NULL argument and so platform_get_drvdata() won't return NULL.

Simplify by removing the if block with the always false condition.
