[PATCH] at86rf230: fix build warning

[Sudip Mukherjee]

e616a00ce786 ("drivers/net/ieee802154/at86rf230.c: seq_printf() now returns NULL")
has removed the usage of the integer "ret" but missed removing the
variable. And we were getting a build warning about "unused variable".

Fixes: e616a00ce786 ("drivers/net/ieee802154/at86rf230.c: seq_printf() now returns NULL")
