[PATCH] rtc: pcf2123: Add missing error code assignment before test

[Christophe JAILLET]

It is likely that checking the result of 'pcf2123_write_reg' is expected
here.
Also fix a small style issue. The '{' at the beginning of the function
is misplaced.

Fixes: 809b453b76e15 ("rtc: pcf2123: clean up writes to the rtc chip")
