syscalls/mremap03: Do not pass MAP_FAILED into mremap()
Running mremap03 -i n got the following errors:
-----------------------------------------------
mremap03 1 TPASS : mremap() Fails, 'old region not mapped', errno 14
mremap03 1 TFAIL : mremap03.c:137: mremap() Fails, 'Unexpected errno 22
...
-----------------------------------------------
When running mremap03 in loops, we passed MAP_FAILED instead of bad
address into mremap().
