mips/tcg: Call probe_write() for CONFIG_USER_ONLY as well
Let's call it also for CONFIG_USER_ONLY. While at it, add a FIXME and get
rid of one local variable.
MIPS code probably needs a bigger refactoring in regards of
ensure_writable_pages(), similar to s390x, so for example, watchpoints
can be handled reliably later. The actually accessed addresses should
be probed only, not full pages.
