xfs: inode unlinked list needs to recalculate the inode CRC
The inode unlinked list manipulations operate directly on the inode buffer, and so bypass the inode CRC calculation mechanisms. Hence an inode on the unlinked list has an invalid CRC. Fix this by recalculating the CRC whenever we modify an unlinked list pointer in an inode, ncluding during log recovery. This is trivial to do and results in unlinked list operations always leaving a consistent inode in the buffer.
