amd/pds_core: core: No need for Null pointer check before kfree

Browse source 
kfree()/vfree() internally perform NULL check on the
pointer handed to it and take no action if it indeed is
NULL. Hence there is no need for a pre-check of the memory
pointer before handing it to kfree()/vfree().

Issue reported by ifnullfree.cocci Coccinelle semantic
patch script.
