parisc: Eliminate memset after alloc_bootmem_pages
alloc_bootmem and related function always return zeroed region of
memory. Thus a memset after calls to these functions is unnecessary.
The following Coccinelle semantic patch was used for making the change:
@@
expression E,E1;
@@
E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...)
... when != E
- memset(E,0,E1);
