bo_bsize: revert r205860 and take an alternative approch in getblk
In r205860 I missed the fact that there is code that strongly assumes
that devvp bo_bsize is equal to underlying provider's sectorsize.
In those places it is hard to obtain the sectorsize in an alternative
way if devvp bo_bsize is set to something else.
So, I am reverting bo_bsize assigment in g_vfs_open.
Instead, in getblk I use DEV_BSIZE block size for b_offset calculation
if vp is a disk vp as reported by vn_isdisk. This should coinside with
vp being a devvp.

X-ToDo: convert bread(devvp) in all fs to use bo_bsize-d blocks
