Subject: [PATCH 05/21] ntp: Convert functions with only two states to bool

From: Thomas Gleixner <tglx@...utronix.de>

is_error_status() and ntp_synced() return whether a state is set or
not. Both functions use unsigned int for it even if it would be a perfect
job for a bool.

Use bool instead of unsigned int. And while at it, move ntp_synced()
function to the place where it is used.

No functional change.
