  ecryptfs: fix kernel panic with null dev_name (2021-04-19 05:50:32 +0000)

Note that there's a "back merge" in here because I forgot to send out a
5.12 PR for two small cleanups that were queued up so my branch was
still on a 5.11-rc release. I did the back merge because the W=1 fixes
needed the idmapped mounts changes that landed in 5.12 and I had hoped
to merge (but didn't) some additional changes to switch over to using a
private clone of the lower mount, which also relied on the idmapped
mounts changes. I won't make a habit out of back merging but wanted to
mention the reasoning since this is the first time I've felt I needed to
do it. Please let me know if it is a problem.

----------------------------------------------------------------
Code cleanups and a bug fix
- W=1 compiler warning cleanups
- Mutex initialization simplification
- Protect against NULL pointer exception during mount
