staging: comedi: addi_apci_3120: remove i_ADDI_Reset()

This driver is now separate from the "common" code used with the
addi-data drivers. There is no need to use i_ADDI_Reset() to call
the correct "reset" function.

Remove the i_ADDI_Reset() function and the 'reset' pointer to the
real function from the boardinfo and just call the function directly
where needed.
