[IA64] sys_mmap doesn't follow posix.1 when parameter len=0

Browse source

In IA64 kernel, sys_mmap calls do_mmap2 and do_mmap2 returns addr if
len=0, which means the mmap sys call succeeds.

Posix.1 says:
The mmap() function shall fail if:
[EINVAL] The value of len is zero. 

Here is a patch to fix it.
