i2c: icy: Remove unused variable new_fwnode in icy_probe()

The last user of new_fwnode was removed, leading to:

    drivers/i2c/busses/i2c-icy.c: In function ‘icy_probe’:
    drivers/i2c/busses/i2c-icy.c:126:24: warning: unused variable ‘new_fwnode’ [-Wunused-variable]
      126 |  struct fwnode_handle *new_fwnode;
	  |                        ^~~~~~~~~~
