[PATCH 1/2] - net/socket.c::sys_bind() cleanup.

["Luiz Fernando N. Capitulino" <lcapitulino@conectiva.com.br>]

 Hi,

 net/socket.c::sys_bind() is a bit complex function, the patch
bellow makes it more clear.

 Note that the code does the same thing, it only makes difference
for the programmer.

 Agains't 2.6.10-rc2.
