x86 ptrace: fix PTRACE_GETFPXREGS error
ptrace has always returned only -EIO for all failures to access registers. The user_regset calls are allowed to return a more meaningful variety of errors. The REGSET_XFP calls use -ENODEV for !cpu_has_fxsr hardware. Make ptrace return the traditional -EIO instead of the error code from the user_regset call.
