nvmem: core: don't check the return value of notifier chain call
blocking_notifier_call_chain() returns the value returned by the last
registered callback. A positive return value doesn't indicate an error
and an nvmem device should correctly register irrespective of any
notifier callback failures. Drop the retval check.
Fixes: bee1138bea15 ("nvmem: add a notifier chain")
