Mark Johnston e02582d1ae Fix synchronization in the IPV6_2292PKTOPTIONS set handler.
The inpcb needs to be locked when we update output packet options.
Otherwise it is possible for the IPV6_2292PKTOPTIONS handler to free
packet option structures while another thread is reading or updating
them.

Note that the option handler is still kind of broken.  For instance it
frees all options before performing privilege checks for individual
options.  However, this can be fixed separately.
