[PATCH 4/6] fs/fs-writeback.c: Add missing annotation for wbc_attach_and_unlock_inode()

[Jules Irenge]

Sparse reports a warning at wbc_attach_and_unlock_inode()

warning: context imbalance in wbc_attach_and_unlock_inode() - unexpected unlock

The root cause is the missing annotation at wbc_attach_and_unlock_inode()
Add the missing __releases(&inode->i_lock) annotation
