Reduce code redundancy in syscall_enter()
Reduce code redundancy in syscall_enter()

* syscall.c [LINUX] (syscall_enter): Move tcp->u_nargs initialization
from arch-specific ifdefs to common code.  Always cache tcp->u_nargs in
a local variable and use it in for() loops.
[IA64, AVR32] Rewrite tcp->u_arg[] initialization using a loop.
