[PATCH v3 2/2] zram: drop unused bio parameter from write helpers

[Cunlong Li <shenxiaogll@gmail.com>]

After the previous fix, zram_bvec_write_partial() always passes NULL
to zram_read_page() and no longer needs the parent bio.  Mirror the
read side (zram_bvec_read_partial() has not taken a bio since commit
4e3c87b9421d ("zram: fix synchronous reads")) and drop the parameter
from zram_bvec_write_partial() and zram_bvec_write().

No functional change.
