Recently rw_page block device operation has been added.  This patchset
implements rw_page operation for zram block device and does some clean-up.

This patch (of 3):

Remove an unnecessary parameter(bio) from zram_bvec_rw() and
zram_bvec_read().  zram_bvec_read() doesn't use a bio parameter, so remove
it.  zram_bvec_rw() calls a read/write operation not using bio, so a rw
parameter replaces a bio parameter.
