Fix comparision to NULL of variable rf_set_sens as per Linux kernel
coding-style. These issues were reported by checkpatch.pl.

CHECK: Comparison to NULL could be written "priv->rf_set_sens"
CHECK: Comparison to NULL could be written "!priv->rf_set_sens"

I would like you to do more.
I you search for rf_set_sens you will see that it is declared as a function.
But there is no definition of the function which will cause an oops when this function is called.

Because there is no definition of the function the priv->rf_set_sens will result always NULL
