dm space map common: make sure new space is used during extend
commit 12c91a5c2d2a8e8cc40a9552313e1e7b0a2d9ee3 upstream.
When extending a low level space map we should update nr_blocks at
the start so the new space is used for the index entries.
Otherwise extend can fail, e.g.: sm_metadata_extend call sequence
that fails:
-> sm_ll_extend
-> dm_tm_new_block -> dm_sm_new_block -> sm_bootstrap_new_block
=> returns -ENOSPC because smm->begin == smm->ll.nr_blocks
