ublk: update UBLK_F_SUPPORT_ZERO_COPY comment in UAPI header
UBLK_F_SUPPORT_ZERO_COPY has a very old comment describing the initial idea for how zero-copy would be implemented. The actual implementation added in commit 1f6540e2aabb ("ublk: zc register/unregister bvec") uses io_uring registered buffers rather than shared memory mapping. Remove the inaccurate remarks about mapping ublk request memory into the ublk server's address space and requiring 4K block size. Replace them with a description of the current zero-copy mechanism.
