[PATCH] lei_store: avoid redundant work on no-op worker spawn

[Eric Wong]

While ->wq_workers_start is idempotent, the pipe creation for
PublicInbox::LeiStoreErr was not and required several extra
syscalls and FD allocations.  Check the correct field required
for SOCK_SEQPACKET workers rather than pipe-based workers.

Fixes: cbc2890cb89b81cb ("lei/store: use SOCK_SEQPACKET rather than pipe")
