No hint update

[sawik-PL]

Short description of problem here
A displayed hint is not updated on the extension state change. Eg.: ext1 displayed instead of ext2 => ext1 or ext2 <=> ext1

Reproduction Steps:
Discovered in a following configuration:

• Cisco 7962 + 7914 addon
• button config:
  • 7962: line(0), feature, speed dial x4 (0-3)
  • 7614: line(1), speed dials... (4-)
• issue appears on the first speed dial (position 3, speed dial instance 0 on 7962)

Investigation
The hint is created in src/sccp_hint.c in function sccp_hint_addSubscription4Device(). Then a deviceType is determined (in a wrong way). Finally, if a device is 7914, a hint is reset (due to some issues with 7914 - according to a comment in the code). I've applied a small fix that works for me.
