add ';' after OSMO_ASSERT()

Currently, OSMO_ASSERT() is defined such that it ends in a semicolon, hence an
added ';' is redundant. However, the usual way this kind of macro should be
defined is

  #define OSMO_ASSERT(x) do { ... } while(0)

so that the compiler requires a trailing semicolon.

To prepare for such a change possibly coming up in libosmocore, add ';' to all
OSMO_ASSERT() users.
