scsi: qla2xxx: Fix race condition between iocb timeout and initialisation
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.
