[PATCH] [media] tuners: One check less in m88rs6000t_get_rf_strength() after error detection

This issue was detected by using the Coccinelle software.

Move the jump label directly before the desired log statement
so that the variable "ret" will not be checked once more
after it was determined that a function call failed.
