block: Don't ignore flags in blk_{,co,aio}_write_zeroes()

Commit 57d6a428 neglected to pass the given flags to blk_aio_prwv(),
which broke discard by WRITE SAME for scsi-disk (the UNMAP bit would be
ignored).

Commit fc1453cd introduced the same bug for blk_write_zeroes(). This is
used for 'qemu-img convert' without has_zero_init (e.g. on a block
device) and for preallocation=falloc in parallels.

Commit 8896e088 is the version for blk_co_write_zeroes(). This function
is only used in qemu-io.
