sparc32: fix register window handling in genregs32_[gs]et()
commit cf51e129b96847f969bfb8af1ee1516a01a70b39 upstream.
It needs access_process_vm() if the traced process does not share
mm with the caller. Solution is similar to what sparc64 does.
Note that genregs32_set() is only ever called with pos being 0
or 32 * sizeof(u32) (the latter - as part of PTRACE_SETREGS
handling).
