[PATCH] use of uninitialized variable fds in main_noinetd()

[Timur R. Mustafin]

Hi.

I started dropbear application on our e2k platform in specific 
"protected mode". Particulary it cheks in runtime for use of 
uninitialized variables. So it finds such case in file svr-main.c with 
variable fds in main_noinetd(). Patch is very small:
