'use mmap = no' option doesn't work anymore

[Garming Sam]

I think it's because of this patch, which Ralph put in.

dbwrap: enable mutexes by default for volatile TDBs

Bug: https://bugzilla.samba.org/show_bug.cgi?id=12891

a70be43246ab74f0a2bbe245ab31f24460b70547

TDB_MUTEX_LOCKING and TDB_NOMMAP are mutually exclusive and so it bails out.


Cheers,

Garming
