board: st: common: update test on misc_read result in command stboard
Update management of misc_read/misc_write, which now returns length of
data after the commit 8729b1ae2cbd ("misc: Update read() and write()
methods to return bytes xfered"): raise a error when the result is not
the expected length.
Fixes: 658fde8a36ff ("board: stm32mp1: stboard: lock the OTP after programming")
