qcacld-3.0: Replace typedef roaming_info_t

The Linux Coding Style enumerates a few special cases where typedefs
are useful, but stresses "NEVER EVER use a typedef unless you can
clearly match one of those rules." The roaming_info_t typedef does not
meet any of those criteria, so replace it with a well named struct. In
the process remove the unused roamingEvent that it contains.
