mfd: stmfx: Improve error message triggered by regulator fault in .remove()
Returning a non-zero value in an i2c remove callback results in the i2c
core emitting a very generic error message ("remove failed (-ESOMETHING),
will be ignored") and as the message indicates not further error handling
is done.
Instead emit a more specific error message and then return zero in
.remove().
The long-term goal is to make the i2c remove prototype return void, making
all implementations return 0 is preparatory work for this change.
