regulator: max77802: Don't ignore return value of current opmode

The return value of regmap_read() of current opmode for regulator was
silently ignored and whatever happened to be in 'val' variable was used
as new opmode. This could lead to using bogus opmode.

Don't ignore what regmap_read() returns. If it fails just fall back to
normal opmode.
