fix the deadlock in xt_qtaguid when enable DDEBUG

When DDEBUG is enabled, the prdebug_full_state() function will try to
recursively aquire the spinlock of sock_tag_list and causing deadlock. A
check statement is added before it aquire the spinlock to differentiate
the behavior depend on the caller of the function.

Bug: 36559739
Test: Compile and run test under system/extra/test/iptables/
