[PATCH 1/2] ipa: Add forward declaration of struct osmo_fd

[Jacob Erlbeck]

A pointer to struct osmo_fd is used in a few prototypes declared in
gsm/ipa.h, but is neither declared explicitly nor is such a
declaration reachable via the given include directives.

This patch adds a forward declaration of this type to ensure proper
compilation.
