ECC layout of some ecc-schemes expect a 'reserve-marker' as specific
byte-position in OOB. But current calculation of oobfree->length does not
consider that for all ecc-schemes.
But in general, for all ecc-schems, OOB bytes from oobfree->offset till end of
OOB region are unused. So this patch fixes oobfree->length calculation.
