From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The call to rhashtable_init is missing an error return check, it is
possible for this to fail various different ways, so fix this by adding
an error check.
Detected by: CoverityScan, CID#1469446 ("Unchecked return value")
Fixes: c6509cc3b3e8 ("mac80211_hwsim: add hashtable with mac address keys for faster lookup")
