ublk: decouple zero copy from user copy
UBLK_F_USER_COPY and UBLK_F_SUPPORT_ZERO_COPY are two different
features, and shouldn't be coupled together.
Commit 1f6540e2aabb ("ublk: zc register/unregister bvec") enables
user copy automatically in case of UBLK_F_SUPPORT_ZERO_COPY, this way
isn't correct.
So decouple zero copy from user copy, and use independent helper to
check each one.
Fixes: 1f6540e2aabb ("ublk: zc register/unregister bvec")
