[PATCH] selftests: mptcp: initialize raw_addr to Null

[Ankit Khushwaha <ankitkhushwaha.linux@gmail.com>]

The "void *raw_addr" is left uninitialized when else path is
followed raising below warning.

mptcp_connect.c:1262:11: warning: variable 'raw_addr' is used
      uninitialized whenever 'if' condition is false
      [-Wsometimes-uninitialized]

so the fix is to assign *raw_addr to NULL to suppress the warning.

compiler used: clang version 21.1.5 (Fedora 21.1.5-1.fc43).
compilation cmd used:
	make -C tools/testing/selftests/net/mptcp CC=clang V=1 -j8

this maybe also be false positive. But somehow clang - 21.1.5
triggering this.
