Sourabh Jain 0843ba4584 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.

Fixes: f4892c68ec ("powerpc/fadump: allocate memory for additional parameters early")
