virtio-blk: Add validation for block size in config space

mainline inclusion
from mainline-v5.14-rc7
commit 82e89ea0
category: bufgix
bugzilla: NA
CVE: NA

--------------------------------

An untrusted device might presents an invalid block size
in configuration space. This tries to add validation for it
in the validate callback and clear the VIRTIO_BLK_F_BLK_SIZE
feature bit if the value is out of the supported range.

And we also double check the value in virtblk_probe() in
case that it's changed after the validation.
