[PATCH] ia64: Return -ENOMEM in ia64_mmap_check() error case

[Joerg Roedel <joro@8bytes.org>]

From: Joerg Roedel <jroedel@suse.de>

The value -ENOMEM is the expected return code for mmap when
the address range verification failes on a MAP_FIXED
request, as stated in the specification:

	[ENOMEM]
	    MAP_FIXED was specified, and the range
	    [addr,addr+len) exceeds that allowed for the
	    address space of a process;

The ia64_mmap_check() function is part of that verification
and should return -ENOMEM too.
