Log Message:
Some removable umass(4) devices don't respond to mode sense page 6, or
simply return zero for logical block size. In either case, use the sector
length reported by READ_CAPACITY instead of defaulting to 512 bytes.

This partially addresses the problems reported in PR port-i386/34707 and
PR kern/34737. Namely the incorrectly reported drive geometry and the
'hanging' issue.

However, since the device in question reports 2048-byte physical sectors
it will remain unusable until DEV_BSIZE is banished.
