Resolves a deadlock that can occur when multiple secondary
processes are starting and stopping. A deadlock can occur because
eal_memalloc_init() is taking a second unnecessary read lock.
If another DPDK process that is terminating enters rte_eal_memory_detach()
and acquires a write lock wait state before the starting process can
acquire it's second read lock then no process will be able to proceed.

Thanks for the report and fix and sorry for the late reply.
Artemy came with a similar report and a more complete fix.
Could you confirm it works for you?
