doc/man: Fix inline formatting in ceph-bluestore-tool.rst

A space is missing between a token with emphasis and the following
token:
- Not consistent with other commands like "show-label" (has space).
- Inline formatting is rendered verbatim in the second occurrence, without
  the formatting being applied.
- Warning from Sphinx.
