Re: [PATCH 11/20] ublk: move offset check out of __ublk_check_and_get_req()

__ublk_check_and_get_req() checks that the passed in offset is within the data length of the specified ublk request. However, only user copy (ublk_check_and_get_req()) supports accessing ublk request data at a nonzero offset. Zero-copy buffer registration (ublk_register_io_buf()) always passes 0 for the offset, so the check is unnecessary. Move the check from __ublk_check_and_get_req() to ublk_check_and_get_req().
