Pretty trivial following other implementations. The existing

dtrace: Fix RISC-V user stack unwinder
The unwind logic was copied from AArch64 which follows the peculiar
AACPS (where, unlike typical RISC architectures, its frame pointer
follows an x86/stack machine-like convention where the frame pointer
points at the bottom of the frame record, not the top). Delete the
pointless riscv_frame struct and fix this.

dtrace: handle page faults in riscv dtrace_trap()
We must detect the correct amount to increment sepc, as it may have been
a compressed instruction that triggered the fault.

dtrace: dtrace_getpcstack() tweaks for riscv
Backtraces for fbt probes are missing the caller's frame. Despite what
the inherited comment claims, we do need to insert this manually on
riscv. In fbt_invop(), set cpu_dtrace_caller to be the return address,
not addr.
We should not increment aframes within this function, since we begin the
main loop by unwinding past the current frame.
Plus some very small comment/style tweaks.
