[DOC-API] Fix CC instance attributes access rights & services access rights

Three documentation fixes are required:

Instance attribute 3 can be set via Network although according to Table 48 in the Current API, the access rule for the attribute when accessed via network is "none"  
-> Access is GET/SET

Using service Kick timer (0x4B) is rejected when using on instance level but according to Table 49 in the current API it shouldn't be rejected.

-> Service only supported at class level

Instance attribute 9 can be accessed via services Get_Attribute_Single and Set_Attribute_Single although it is deactivated by default, according to the current API.

-> Attribute is not deactivated and has GET/SET access.
