sfc: suppress duplicate nvmem partition types in efx_ef10_mtd_probe
[ Upstream commit 3366463513f544c12c6b88c13da4462ee9e7a1a1 ]
Use a bitmap to keep track of which partition types we've already seen;
for duplicates, return -EEXIST from efx_ef10_mtd_probe_partition() and
thus skip adding that partition.
Duplicate partitions occur because of the A/B backup scheme used by newer
sfc NICs. Prior to this patch they cause sysfs_warn_dup errors because
they have the same name, causing us not to expose any MTDs at all.
