[PATCH 1/2] bootstd: rauc: no valid slot fallback: fix info msg to reflect real flow

[Andreas Pretzsch]

If there is no more active slot found in find_active_slot(), like when
all slots in BOOT_ORDER have a count of 0, the counters are reset to their
default value CONFIG_BOOTMETH_RAUC_DEFAULT_TRIES. The BOOT_ORDER is _not_
changed, which is logically correct (especially for the case when there is
only one (active) slot set, e.g. BOOT_ORDER only contains 'B', probably due
to RAUC option prevent-late-fallback being set). Resetting the counters of
inactive slots also does not harm here, and is fine as a generic solution.

But the log_info statement in this scenario
  INFO: Resetting boot order and all slot tries
is incorrect. Change this to
  INFO: Resetting all slot tries to 3
with the 3 being inserted by CONFIG_BOOTMETH_RAUC_DEFAULT_TRIES.
