The other callers to blk_set_enable_write_cache() in this file
already check for s->blk == NULL.

I think this is a bugfix that should be back ported to stable
releases.
I also think this should be done in xen's copy of QEMU for 4.5 with
back port(s) to active stable releases.
Note: In 2.1 and earlier the routine is
bdrv_set_enable_write_cache(); variable is s->bs.
