Gleb Natapov 8bfcfa464a Don't call free(), or library functions that may call free() inside (such as
ibv_dereg_mr() for instance) from ptmalloc callback. Call to free() from the
callback causes deadlock. Notice what should be unregistered inside the callback
and do actual cleanup at the next call to mpool->register().
