inet: Fix getnameinfo (NI_NOFQDN) race condition (BZ#28566)
The 'not_first' is accessed on nrl_domainname() in a non atomically
way, although it is only updated after the lock is taken.
This patch fix the double-checked locking by using acquire-release
atomic operation instead of plain load and by moving the 'not_first'
store only after 'domain' is actually set.
Checked on x86_64-linux-gnu.
