[LTP] [PATCH] mmapstress03: consider passed when returning EINVAL in the large mmap test.

[LTP] [PATCH] mmapstress03: consider passed when returning EINVAL in the large mmap test.

[nobuhiro]

Some architectures may return EINVAL instead of ENOMEM.
This should also be ok according to mmap manual:
EINVAL We don't like addr, length, or offset (e.g., they are too large, or not aligned on a page boundary).
