ksmbd: increase session and share hash table bits

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Increases the number of bits for the hash table from 3 to 12.
The thousands of sessions and shares can be connected.
So the current 3-bit size can lead to frequent hash collisions.
