Subject: [PATCH] zonefs: Clear inode information flags on inode creation
Ensure that the i_flags field of struct zonefs_inode_info is cleared to
0 when initializing a zone file inode, avoiding seeing the flag
ZONEFS_ZONE_OPEN being incorrectly set.
Fixes: b5c00e975779 ("zonefs: open/close zone on file open/close")
