IB/mthca: multiple fixes for multicast group handling

Multicast group management fixes:
. Fix leak of mailbox memory in error handling on multicast group operations.
. Free AMGM indices at detach and in attach error handling.
. Fix amount to shift for aligning next_gid_index in mailbox: it
  starts at bit 6, not bit 5.
. Allocate AMGM index after end of MGM table, in the range num_mgms to
  multicast table size - 1. Add some BUG_ON checks to catch cases
  where the index falls in the MGM hash area.
. Initialize the list of QPs in a newly-allocated group from AMGM to 0
  This is necessary since when a group is moved from AMGM to MGM (in the
  case where the MGM entry has been emptied of QPs), the AMGM entry is
  not reset to 0 (and we don't want an extra command to do that).
