Consider the test to be a success as long as the initializing pattern is found at least once per metaslab. This indicates that at least part of the free space was initialized. Ideally we'd check that the pattern was written to all free space but that's much tricker so this check is a reasonable compromise. Using a here-string to feed the loop in this test causes an empty string to still trigger the loop so we miss the `spacemaps=0` case. Pipe into the loop instead. While here, we can use `zpool wait -t initialize $TESTPOOL` to wait for the pool to initialize.

Description
Consider the test to be a success as long as the initializing pattern
is found at least once per metaslab. This indicates that at least
part of the free space was initialized. Ideally we'd check that the
pattern was written to all free space but that's much trickier so this
check is a reasonable compromise.
Using a here-string to feed the loop in this test causes an empty
string to still trigger the loop so we miss the
spacemaps=0case.Pipe into the loop instead.
While here, we can use
zpool wait -t initialize $TESTPOOLto wait forthe pool to initialize.
How Has This Been Tested?
Locally on Linux and FreeBSD. Pending confirmation from the CI.
