[PATCH 6/9] regulator: tps65217-regulator: Use the returned value of tps65217_reg_read()

Until now the aforementioned return value has been ignored.
Previous and current calls to tps65217_reg_read() return
instantly when the value is not 0, so let's do that.

Fixes the following W=1 warning:

 drivers/regulator/tps65217-regulator.c: In function ‘tps65217_regulator_probe’:
 drivers/regulator/tps65217-regulator.c:227:9: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]
 227 | int i, ret;
 | ^~~
