socket: Explicit narrowing type cast and add missing static keywords (#1539)

Browse Source 
While compiling the file wasi_socket_ext.c with pedantic options (typically
`-Wimplicit-int-conversion` and `-Wmissing-prototypes`), some warnings are raised.

This PR addresses those warnings by adding missing static statements before
functions and explicitly casting a narrowing conversion.

And fix the error handling after calling getpeername.
