Steven Noonan 863522b1f9 dsl_scan_scrub_cb: don't double-account non-embedded blocks
We were doing count_block() twice inside this function, once
unconditionally at the beginning (intended to catch the embedded block
case) and once near the end after processing the block.

The double-accounting caused the "zpool scrub" progress statistics in
"zpool status" to climb from 0% to 200% instead of 0% to 100%, and
showed double the I/O rate it was actually seeing.

This was apparently a regression introduced in commit 00c405b4b5,
which was an incorrect port of this OpenZFS commit:
