powerpc: Fix ptrace compat wrapper for FPU register access
The ptrace compat wrapper mishandles access to the fpu registers. The
PTRACE_PEEKUSR and PTRACE_POKEUSR requests miscalculate the index into
the fpr array due to the broken FPINDEX macro. The
PPC_PTRACE_PEEKUSR_3264 request needs to use the same formula that the
native ptrace interface uses when operating on the register number (as
opposed to the 4-byte offset). The PPC_PTRACE_POKEUSR_3264 request
didn't take TS_FPRWIDTH into account.
