control: initialize element channel values according to identification number at adding a new element

Browse source 
In ALSA control core, there're two ways to identify elements. One is by
numid. Another is by name/index. The former way is lighter than the latter
way.

In control API, after adding elements by snd_ctl_elem_add_integer() and
snd_ctl_elem_add_integer64(), these functions initialize value of each
channel. When executing this operation, used ID information is still given
by applications. Although, in this time, the element can be identified
according to numid.

This commit uses the numid instead of name/index pair.
