Subject[PATCH] kdb: use bool for binary state indicators
Date
 defcmd_in_progress  is the state trace for command group processing
- within a command group or not - usable is an indicator if a command
set is valid (allocated/non-empty) - so use a bool for those binary
indication here.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

Found during code review.
Not a functional issue - just type correctness.

Patch was compile tested with: x86_64_defconfig + CONFIG_KGDB=y,
CONFIG_KGDB_KDB=y
(some sparse/smatch warnings not related to the proposed change though)

Patch is against 4.18-rc5 (localversion-next is next-20180720)
