smb3: move defines for query info and query fsinfo to smbfs_common 



Includes moving to common code (from cifs and ksmbd protocol related
headers)
- query and query directory info levels and structs
- set info structs
- SMB2 lock struct and flags
- SMB2 echo req

Also shorten a few flag names (e.g. SMB2_LOCKFLAG_EXCLUSIVE_LOCK
to SMB2_LOCKFLAG_EXCLUSIVE)
