x86/setup/crash: Check memblock_reserve() retval
memblock_reserve() can fail but the crashkernel reservation code
doesn't check that and this can lead the user into believing
that the crashkernel region was actually reserved. Make sure we
check that return value and we exit early with a failure message
in the error case.
