[PATCH] staging: fix comedi build when ISA_DMA_API is enabled but COMEDI_PCI is not enabled

[Randy Dunlap]

From: Randy Dunlap <rdunlap at xenotime.net>

Fix build when CONFIG_ISA_DMA_API is enabled but
CONFIG_COMEDI_PCI[_DRIVERS] is not enabled.
Fixes these build errors:

drivers/staging/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
drivers/staging/comedi/drivers/ni_labpc.c:1351: error: implicit declaration of function 'labpc_suggest_transfer_size'
drivers/staging/comedi/drivers/ni_labpc.c: At top level:
drivers/staging/comedi/drivers/ni_labpc.c:1802: error: conflicting types for 'labpc_suggest_transfer_size'
drivers/staging/comedi/drivers/ni_labpc.c:1351: note: previous implicit declaration of 'labpc_suggest_transfer_size' was here

Greg, I had previously said that this patch was not needed since
you had merged a larger patch, but I had another build error which
this patch fixes, so it is now needed in mainline.
