[PATCH 34/41] staging: comedi: addi_apci_1516: fix i_APCI1516_ReadWatchdog()

[H Hartley Sweeten]

This function is used by the watchdog subdevice to read the status of
the watchdog. Rename the CamelCase function to apci1516_wdog_insn_read
and fix the function to return the status value insn->n times like
the comedi core expects.
