[Qemu-devel] [PATCH] net/socket: Fix compiler warning (regression for MinGW)

[Stefan Weil <sw@weilnetz.de>]

Add a type cast which was removed by commit
213fd5087e2e4e2da10ad266df0ba950cf7618bf again.

Without it, MinGW compilers complain:

net/socket.c:136: warning:
 pointer targets in passing argument 2 of ‘sendto’ differ in signedness
/usr/lib/gcc/amd64-mingw32msvc/4.4.4/../../../../amd64-mingw32msvc/include/winsock2.h:1313: note:
 expected ‘const char *’ but argument is of type ‘const uint8_t *’
