Fix mismerge in r337196.
ZoL did the same mistake, and fixed it with separate commit863522b1f9
: 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 commit00c405b4b5
