Baokun Li 551667f99b ext4: goto right label 'out_mmap_sem' in ext4_setattr() 
commit 7e91ae31e2 upstream.

Otherwise, if ext4_inode_attach_jinode() fails, a hung task will
happen because filemap_invalidate_unlock() isn't called to unlock
mapping->invalidate_lock. Like this:

EXT4-fs error (device sda) in ext4_setattr:5557: Out of memory
INFO: task fsstress:374 blocked for more than 122 seconds.
      Not tainted 6.14.0-rc1-next-20250206-xfstests-dirty #726
