[PATCH 1/4] spi: Move queue data structure initialisation to main master init

[Mark Brown <broonie-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Since most devices now do use the standard queue and in order to avoid
initialisation ordering issues being introduced by further refactorings
to improve performance move the initialisation of the queue and the lock
for it to the main master allocation.
