smbd: replace CHECK_WRITE() macro with calls to check_any_access_fsp()

smbd: replace CHECK_WRITE() macro with calls to check_any_access_fsp()

The additional check if fd underlying fd is valid and not -1 should not be done
at this place. I actually would prefer an write to fail with EBADF if this
happens, as it's likely easier to debug why this happened. These days we should
always have a valid fd.
