mtd: cfi_cmdset_0002: fix SEGV unlocking multiple chips
commit 5fdfc3dbad099281bf027a353d5786c09408a8e5 upstream.
cfi_ppb_unlock() tries to relock all sectors that were locked before
unlocking the whole chip.
This locking used the chip start address + the FULL offset from the
first flash chip, thereby forming an illegal address. Fix that by using
the chip offset(adr).
