Subject: [PATCH -next] Input: synaptics-rmi4 - Remove set but not used variable 'sensor_flags'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/input/rmi4/rmi_f12.c: In function rmi_f12_read_sensor_tuning:
drivers/input/rmi4/rmi_f12.c:76:6: warning: variable sensor_flags set but not used [-Wunused-but-set-variable]

It's not used since introduction in
commit b43d2c1e9353 ("Input: synaptics-rmi4 - add support for F12")
