qcacmn: Avoid reset of reg rules in soc private object

In the current implementation, reg rules stored in mas_chan_params of soc
for each phy id are reset in regulatory_pdev_obj_created_notification()
and in regulatory_psoc_close().

In WLAN restart sequence, regulatory_psoc_close() is invoked and processing
of WMI_REG_CHAN_LIST_CC_EVENTID is ignored, if the country code matches
with existing country code in soc reg private object. Since reg_rules
in mas_chan_params of soc are reset there are no reg_rules for pdev
resulting in no indication (regulatory_set_wiphy_regd()) to cfg80211.

To fix this, avoid reset of psoc reg rules.
