When remounting with the no_bulk_read option,
there is a problem accessing the "bulk_read buffer(bu.buf)"
which has already been freed.
If the bulk_read option is enabled,
ubifs_tnc_bulk_read uses the pre-allocated bu.buf.
While bu.buf is being used by ubifs_tnc_bulk_read,

This patch changes parameter of valid_io_request for common usage.
The purpose of valid_io_request() is to determine if bio request is
valid or not.
This patch use I/O start address and size instead of a BIO parameter
for common usage.

This patch removes 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.
