qcacmn: Skip CFR umac handling when feature is disabled

Browse source 
Retrieve the INI option to disable CFR and store the
same in pdev feature ext caps.

When CFR feature is disabled -
1. Skip pdev/peer cfr object allocations
2. Skip CFR SRNG allocations
3. Skip WMI registration for DBR and TX completion events
