NFSv4/pNFS: Clear NFS_INO_LAYOUTCOMMIT in pnfs_mark_layout_stateid_invalid
[ Upstream commit e0f8058f2cb56de0b7572f51cd563ca5debce746 ]
Fixes a crash when layout is null during this call stack:
write_inode
-> nfs4_write_inode
-> pnfs_layoutcommit_inode
pnfs_set_layoutcommit relies on the lseg refcount to keep the layout
around. Need to clear NFS_INO_LAYOUTCOMMIT otherwise we might attempt
to reference a null layout.
Fixes: fe1cf9469d7bc ("pNFS: Clear all layout segment state in pnfs_mark_layout_stateid_invalid")
