Commit edd8ce67, Use extended crashkernel command line on ppc64,
resulted in reserve_crashkernel() attempting to reserve a 1 byte
crashkernel area when no no crashkernel reservation is requested.
This results in the following bogus messages:
Crash kernel location must be 0x2000000
Reserving 0MB of memory at 32MB for crashkernel
The problem is that when crashk_res.start and crashk_res.end are
both 0, the crash_size is computed to be 1 byte.
Revert back to using the value of crashk_res.start to determine
if crashkernel memory is being reserved, rather than the computed
crash_size.
