sparc64: fix misuses of access_process_vm() in genregs32_[sg]et()
[ Upstream commit 142cd25293f6a7ecbdff4fb0af17de6438d46433 ]
We do need access_process_vm() to access the target's reg_window.
However, access to caller's memory (storing the result in
genregs32_get(), fetching the new values in case of genregs32_set())
should be done by normal uaccess primitives.
Fixes: ad4f95764040 ([SPARC64]: Fix user accesses in regset code.)
