Ian Abbott f44af347f7 staging: comedi: addi_apci_1564: check INSN_CONFIG_DIGITAL_TRIG shift 
commit 926234f1b8434c4409aa4c53637aa3362ca07cea upstream.

The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked.  Shift amounts greater than or equal to 32 will result in
undefined behavior.  Add code to deal with this.
