use proper type for RPMB blocks_cnt

The JEDEC standard is confusing. The number of max blocks for reading
RPMB is determined by CMD23 which can hold an unsigned int and not only
u16. It is true that the current maximum is 64K of blocks, yet this may
be extended in the future. Let's not apply a limit here which should be
checked by the card.
