Nagaraj Annaiah 221989d875 osi core: Fix compiler warnings for HVRTOS 
Issue: Unused variables are treated as errors with HVRTOS compiler.

Fix:
1. Add unused attributes macro for unused function arguments.
2. Fix typecast errors.
3. Add flag to check if ethernet server status, this is needed to
   skip check for function pointer validation.

Bug 3562777
