[PATCH] lmb: notify when adjacent regions are added

[Caleb Connolly]

lmb_add_region() returns a positive integer if the added regions causes
existing regions to be coalesced. We still want to notify the EFI
subsystem about these added regions though, so adjust lmb_add() to only
bail on errors.

This fixes EFI memory allocation on boards with adjacent memory banks as is the
case on several Qualcomm boards like the RB3 Gen 2.

Fixes: 2f6191526a13 (lmb: notify of any changes to the LMB memory map)
