ksmbd: Annotate struct copychunk_ioctl_req with __counted_by_le()
Add the __counted_by_le compiler attribute to the flexible array member
Chunks to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.
Change the data type of the flexible array member Chunks from __u8[] to
struct srv_copychunk[] for ChunkCount to match the number of elements in
the Chunks array. (With __u8[], each srv_copychunk would occupy 24 array
entries and the __counted_by compiler attribute wouldn't be applicable.)
Use struct_size() to calculate the size of the copychunk_ioctl_req.
Read Chunks[0] after checking that ChunkCount is not 0.
