sparc: simplify module_alloc()
Define MODULES_VADDR and MODULES_END as VMALLOC_START and VMALLOC_END
for 32-bit and reduce module_alloc() to
__vmalloc_node_range(size, 1, MODULES_VADDR, MODULES_END, ...)
as with the new defines the allocations becomes identical for both 32
and 64 bits.
While on it, drop unused include of <linux/jump_label.h>
