drivers: regulator: npm6001: Fix compiler warning

Balaji Srinivasan · MaureenHelm · commit d9b3ffa5eafc · 2024-05-13T09:54:48.000-05:00
This patch fixes a compiler warning about the val being used
uninitialized. The previously present if check did not seem to satisfy
compiler. Hence the val is now explictly initialized.
