[PATCH] [bcachefs-tools] Cosmetic fixes for device resize-journal

[Chris Webb <chris@arachsys.com>]

Correct the operation name from 'journal-resize' to 'resize-journal' in the
bcachefs usage summary, matching the command that is actually implemented.

Fix the size argument so it isn't optional. Defaulting to the entire device
makes sense for 'device resize', to automatically expand the fs to fill the
block device. However, it is never meaningful (or possible) to expand the
journal to the full disk.
