72d935020e fpga: fpga-mgr: make write_complete() op optional 
An FPGA manager should not be required to provide a
write_complete function if there is nothing.  Move
the op check to the existing wrapper.
Default to success and remove noop function.

498ddaa3b4 fpga: zynqmp-fpga: Correctly handle error pointer 
Fixes the following static checker errors:

drivers/fpga/zynqmp-fpga.c:50 zynqmp_fpga_ops_write()
error: 'eemi_ops' dereferencing possible ERR_PTR()

drivers/fpga/zynqmp-fpga.c:84 zynqmp_fpga_ops_state()
error: 'eemi_ops' dereferencing possible ERR_PTR()

Note: This does not handle the EPROBE_DEFER value in a
      special manner.
