ublk: don't return 0 in case of any failure
Commit 2d786e66c966 ("block: ublk: switch to ioctl command encoding")
starts to reset local variable of 'ret' as zero, then if any failure
happens when handling the three IO commands, 0 can be returned to ublk
server.
Fix it by returning -EINVAL in case of command handling failure.
