powerpc/fadump: skip parameter area allocation when fadump is disabled 



Fadump allocates memory to pass additional kernel command-line argument
to the fadump kernel. However, this allocation is not needed when fadump
is disabled. So avoid allocating memory for the additional parameter
area in such cases.
