Richard Purdie ccc5ccc17f linux-user/mmap: Avoid asserts for out of range mremap calls 
If mremap() is called without the MREMAP_MAYMOVE flag with a start address
just before the end of memory (reserved_va) where new_size would exceed
it (and GUEST_ADDR_MAX), the assert(end - 1 <= GUEST_ADDR_MAX) in 
page_set_flags() would trigger.

Add an extra guard to the guest_range_valid() checks to prevent this and
avoid asserting binaries when reserved_va is set.

This meant a bug I was seeing locally now gives the same behaviour 
regardless of whether reserved_va is set or not.
