JDK-8193105 - Print error code when map_memory_to_file() fails
Description
util_posix_fallocate() is implemented differently for OSX and other.
Other version directly calls posix_fallocate() and returns error code when fails. However, OSX version returns -1 with setting errno when fails. 

Current os::map_memory_to_file() checks return value and prints as an error which doesn't fit in OSX version.
