        src/sys/miscfs/specfs: spec_vnops.c

Log Message:
when determining I/O block size for VBLK device, only use pi_bsize
returned by DIOCGPARTINFO if it's bigger than DEV_BSIZE and less
than MAXBSIZE (MAXPHYS)

fixes panic "buf mem pool index 8" in buf_mempoolidx() when the
disklabel contains bsize 128KB and something reads the block device -
buffer cache can't allocate bufs bigger than MAXPHYS
