Since commit 95b9c27c81 ("linux-user: Remove unused handle_vm86_fault")
a bunch of other "static inline" function are now unused, too. Clang
warns about such unused "static inline" functions in .c files, so the
build currently breaks when compiling with "--enable-werror". Remove
the unused functions to get it going again.
Fixes: 95b9c27c81 ("linux-user: Remove unused handle_vm86_fault")
