Alex Bennée 8ef618859c linux-user: detect overflow of MAP_FIXED mmap
Relaxing the restrictions on 64 bit guests leads to the user being
able to attempt to map right at the edge of addressable memory. This
in turn lead to address overflow tripping the assert in page_set_flags
when the end address wrapped around.

Detect the wrap earlier and correctly -ENOMEM the guest (in the
reported case LTP mmap15).
