md: dm-zoned-target: Initialize return variable r to avoid uninitialized use
[ Upstream commit 487767bff572d46f7c37ad846c4078f6d6c9cc55 ]
Fix Smatch-detected error:
drivers/md/dm-zoned-target.c:1073 dmz_iterate_devices()
error: uninitialized symbol 'r'.
Smatch detects a possible use of the uninitialized variable 'r' in
dmz_iterate_devices() because if dmz->nr_ddevs is zero, the loop is
skipped and 'r' is returned without being set, leading to undefined
behavior.
Initialize 'r' to 0 before the loop. This ensures that if there are no
devices to iterate over, the function still returns a defined value.
