__peernet2id_alloc() was used for both plain lookups and for netns ID
allocations (depending the value of '*alloc'). Let's separate lookups
from allocations instead. That is, integrate the lookup code into
__peernet2id() and make peernet2id_alloc() responsible for allocating
new netns IDs when necessary.
This makes it clear that __peernet2id() doesn't modify the idr and
prepares the code for lockless lookups.
Also, mark the 'net' argument of __peernet2id() as 'const', since we're
modifying this line.
