erts: Fix confusion of callbacks destroying_mbc() vs remove_mbc()
Problem #1 Goodfit was crippled by the fact that destroying_mbc() was called _before_ the carriers was unlinked from mbc_list. Problem #2 destroying_mbc() was called for carriers that later could be resurrected from dc_list without a matching call to creating_mbc(). This was mostly a practical problem for the new test case alloc_SUITE:migration that use the callbacks to create/destroy a mutex. Solution: destroying_mbc() is now only called just before a carrier is destroyed (deallocated or put in mseg cache). remove_mbc() is called both (like before) when inserted into cpool but now also when last block is freed and mbc is scheduled for destruction but may later be resurrected from dc_list.
