Remove obsolete DBus dispatch lock

In c2049f67e4cfe5f09e1b033b910cb37d043a287e, all DBus I/O was
moved into a service thread. The dispatch lock used to protect
DBus I/O in the threading setup before that commit. It is not
needed anymore.
No discernible difference in QtDBus benchmarks, roughly 500
bytes code size reduction on AMD64. The main point is to reduce
confusion from unnecessary code.
