riscv: module: remove relocation_head rel_entry member allocation

Browse source

[ Upstream commit 03f0b54853 ]

relocation_head's list_head member, rel_entry, doesn't need to be
allocated, its storage can just be part of the allocated relocation_head.
Remove the pointer which allows to get rid of the allocation as well as
an existing memory leak found by Kai Zhang using kmemleak.
