probe_write() was added in there in 3b4afc9e75a to be moved out
to accel/tcg/cputlb.c in 3b08f0a9254, and was later refactored
as probe_access() in c25c283df0f.
Since it is a TCG specific helper, add a stub to avoid failures
when building without TCG, such:

There is no need for a stub, since tb_invalidate_phys_addr can be excised
altogether when TCG is disabled. This is a bit cleaner since it avoids
using code that is clearly specific to user-mode emulation (it calls
mmap_lock/unlock) for the !CONFIG_TCG case.
