uprobes: Pass probed vaddr to arch_uprobe_analyze_insn()
On RISC architectures like powerpc, instructions are fixed size.
Instruction analysis on such platforms is just a matter of
(insn % 4). Pass the vaddr at which the uprobe is to be inserted so
that arch_uprobe_analyze_insn() can flag misaligned registration
requests.
