qcacmn: Refactor the code to update the conc_system_pref

Refactor the code to dynamically change the conc_system_pref.
Whenever user changes conc_system_pref from application,
driver is overwriting the conc_system_pref which is getting
populated from ini file. Once it is overwritten there is no way
to get the configured value for this setting. So add a new
variable to hold the value of conc_system_pref without disturbing
default value read from ini file.
