qla2x00_init_timer() calls add_timer() on the iocb timeout timer,
which means the timeout function pointer and any data that the
function depends on must be initialised beforehand.
Move this initialisation before each call to qla2x00_init_timer(). In
some cases qla2x00_init_timer() initialises a completion structure
needed by the timeout function, so move the call to add_timer() after
that.
