Harald Welte 8398bccb0b lib/netns: Fix up error paths 
The error handling in the code was doing exactly what one would not
expect.  If we switch to a netns and then encounter an error, we
obviously have to switch back to the original netns before returning.

Likewise, if we temporarily change the signal mask, we need to switch
back to the original one before returning.

Harald Welte 61b010c25a lib/netns: OSMO_ASSERT() if user doesn't call init_netns() 
It is vital that init_netns() is called first in order to initialize
default_nsfd.
