qcacld-3.0: Properly export SME P2P APIs

There are currently several SME P2P APIs which do not have their
prototypes exported in header files; instead sme_api.c has "extern"
declarations for these APIs. This prevents the compiler from verifying
that the implementations match the declarations, and causes a warning
when the driver is built using -Wmissing-prototypes.  To address this
issue properly export all P2P APIs.
