misc: at25: Don't copy garbage to the at25->chip in FRAM case
Even if we know that we are going to fill everything later on
it's bad style and fragile to copy garbage from the stack to
the data structure that will be used in the driver.
Fixes: fd307a4ad332 ("nvmem: prepare basics for FRAM support")
