mruby-io: fix incorrect pointer access in io.c

Browse Source 
In the Windows-specific code path for IO.popen, the variable 'p'
is a struct, not a pointer. The code was using 'p->klass' to
access a member, which is incorrect and causes a build failure
on Windows. This has been corrected to use the 'klass' argument
directly.
