[PATCH] mount: don't canonicalize the source of a pseudofs

[Dave Reisner <d@falconindy.com>]

In line with previous patches, the source of a pseudofs is strictly
semantic; do not attempt to resolve it to a filesystem path.

As a side effect of this, nspec needs to be initialized to NULL since
it may not be assigned null by spec_to_devname when the FS is deemed
a pseudofs.

This wasn't as evil as I thought, after all...
