net/mlx5: HWS, fix reformat pool creation race
mlx5_fs_get_pr_encap_pool() inserts a new pool when the lookup misses.
Two callers allocating the first reformat of a size at once both
create one and the second fails with -EBUSY. TC serializes these
allocations under encap_tbl_lock while RDMA flow actions on the FDB
don't.
Sashiko AI review of an earlier series spotted this issue.
Tested for regressions on ConnectX-7 with firmware 28.48.1000.
Fixes: aecd9d1020e3 ("net/mlx5: fs, add HWS packet reformat API function")
