Commit ac0126a01735 ("soc: qcom: cmd-db: replace strncpy() with
strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine
device. From printouts I see that at bootup the function is called
with an id of "lnbclka2" which is 8 bytes big.
Previously all 8 bytes of this string were copied to the
destination. Now only 7 bytes will be copied since strscpy_pad() saves
a byte for '\0' termination.
We don't need the '\0' termination in the destination. Let's go back
to strncpy(). According to the warning:
If a caller is using non-NUL-terminated strings, strncpy() can still
be used, but destinations should be marked with the __nonstring
attribute to avoid future compiler warnings.
...so we'll do that.
