ksmbd: preserve data during overlapping copy chunk
Copying an overlapping range within the same file through
do_splice_direct() can overwrite source data that has not yet been
read. This corrupts the destination when the target range starts
inside and after the source range.
Handle overlapping ranges with a bounded temporary buffer. Copy from
the end when the destination follows the source and from the beginning
otherwise, providing memmove semantics without allocating the entire
copy length.
