ctl: use consistent name for second argument of snd_ctl_elem_read/write

Browse source 
Second argument of these functions has three different names in
documentation/header/code (obj/control/value). This easily causes users'
confusion.

This commit applies consistent names for the arguments.

Fixes: 90020c05f8 ('ctl: improve comments for handling element data')
