[LMB]: Fix lmb allocation regression.

Changeset d9024df ("[LMB] Restructure
allocation loops to avoid unsigned underflow") removed the alignment
of the 'size' argument to call lmb_add_region() done by __lmb_alloc_base().

In doing so it reintroduced the bug fixed by changeset
eea89e1 ("[LMB]: Fix bug in
__lmb_alloc_base().").

This puts it back.
