Subject: [PATCH] staging: comedi: hwdrv_apci3120: fix 'b_AiCyclicAcquisition'
 usage

This private data member is set when an analog input async command is
started by apci3120_cyclic_ai() and cleared when the command finishes
or is canceled.

Rename the CamelCase member to 'ai_running' and convert it to a
bit-field flag.

Remove the unnecessary clearing of the flag before or after calling
apci3120_cancel().
