Additional SMB3.1.1 FSCTLs

Looking at MS-FSCC, I noticed some FSCTLs we don't use in current
cifs.ko but Windows supports:
2.3.13 FSCTL_FILE_LEVEL_TRIM
2.3.29 FSCTL_GET_RETRIEVAL_POINTER_COUNT
2.3.41 FSCTL_OFFLOAD_READ Request
2.3.43 FSCTL_OFFLOAD_WRITE
2.3.55 FSCTL_QUERY_FILE_REGIONS
2.3.63 FSCTL_RECALL_FILE (maybe add an smbinfo command for this?)
2.3.87 FSCTL_SET_ZERO_ON_DEALLOCATION (maybe add an smbinfo command for this?)

Do you see any of these that we should be using in cifs.ko or userspace tools?
