dax: make 'wait_table' global variable static
The global 'wait_table' variable is only used within fs/dax.c, and generates the following sparse warning: fs/dax.c:39:19: warning: symbol 'wait_table' was not declared. Should it be static? Make it static so it has scope local to fs/dax.c, and to make sparse happy.
