ext4: set EXT4_STATE_NO_EXPAND in ext4_evict_inode

An inode being evicted will never need its extra isize expanded.  Set
EXT4_STATE_NO_EXPAND before ext4_mark_inode_dirty() in ext4_evict_inode()
to make this explicit and prevent any unnecessary work in
ext4_try_to_expand_extra_isize().

This also provides defense-in-depth for the s_writepages_rwsem deadlock
during mount-time orphan cleanup, ensuring the expand path is blocked
for inodes under eviction regardless of how they are reached.
