[PATCH 048/108] staging: comedi: addi_apci_3120: remove private data 'ui_AiReadData'

[H Hartley Sweeten]

This member of the private data was used to return analog input samples that
were acquired for the (*insn_read) using interrupts. The interrupt support
code for the (*insn_read) has been removed. Remove this unused member from
the private data.
