Fixes this coverity issue:
*** CID

/src/rculfhash.c: 1950 in cds_lfht_resize()
1944 }
1945
1946 void cds_lfht_resize(struct cds_lfht *ht, unsigned long new_size)
1947 {
1948 resize_target_update_count(ht, new_size);
1949 CMM_STORE_SHARED(ht->resize_initiated, 1);
>>> CID

>>> Calling "pthread_mutex_lock" without checking return value (as is done elsewhere 44 out of 50 times).
1950 pthread_mutex_lock(&ht->resize_mutex);
1951 _do_cds_lfht_resize(ht);
1952 pthread_mutex_unlock(&ht->resize_mutex);
