memstick: remove deprecated use of pci api

Browse Source 
Replace occurences of the pci api by appropriate call to the dma api.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr)

@deprecated@

position p;

  pci_dma_supported@p ( id, ...)
