ecryptfs: remove debug as mount option, and warn if set via modprobe
ecryptfs_debug really should not be a mount option; it is not per-mount,
but rather sets a global "ecryptfs_verbosity" variable which affects all
mounted filesysytems. It's already settable as a module load option,
I think we can leave it at that.
Also, if set, since secret values come out in debug messages, kick
things off with a stern warning.
