interface: add 'discard-secure' and BLKIF_DISCARD_SECURE

Alter the 'reserved' uint8_t to be used a 'flag'. We use only for one
flag: BLKIF_DISCARD_SECURE.

That flag can only be set if the backend has set 'discard-secure' to
one.  If backend has not set 'discard-secure' to one, that flag will
have no effect.
