block: blk-zoned: fix zwplug refcount leak on write error path
e706ffd 
blk_zone_wplug_handle_write() increments zwplug->ref via kref_get()
when preparing to handle a zone write. On the error path where
blk_zone_wplug_handle_write_noalloc() fails, the function returns
without calling kref_put() on zwplug->ref, leaking the reference.

Add kref_put(&zwplug->ref, ...) on the error path to properly release
the reference.
