net/bnxt: release HWRM lock before returning

Browse Source 
The function bnxt_vnic_rss_configure_thor() returns early when
all receive queues are stopped without releasing the hwrm
spinlock, which causes subsequent HWRM operations to hang. Fix
by ensuring that the lock is released before returning from
this function.
