Serapheim Dimitropoulos 65a91b166e metaslab_verify_weight_and_frag() shouldn't cause side-effects 
`metaslab_verify_weight_and_frag()` a verification function and
by the end of it there shouldn't be any side-effects.

The function calls `metaslab_weight()` which in turn calls
`metaslab_set_fragmentation()`. The latter can dirty and otherwise
not dirty metaslab fro the next TXGand set `metaslab_condense_wanted`
if the spacemaps were just upgraded (meaning we just enabled the
SPACEMAP_HISTOGRAM feature through upgrade).

This patch adds a new flag as a parameter to `metaslab_weight()` and
`metaslab_set_fragmentation()` making the dirtying of the metaslab
optional.
