[2/4] mtd: core: fix nvmem error reporting
Commit Message
The master MTD will only have an associated device if
CONFIG_MTD_PARTITIONED_MASTER is set, thus we cannot use dev_err() on
mtd->dev. Instead use the parent device which is the physical flash
memory.
Fixes: 4b361cfa8624 ("mtd: core: add OTP nvmem provider support")
