ksmbd: fix SMB2 byte-range lock end offset
SMB2 describes a byte-range lock using an offset and a length, while
Linux file_lock uses an inclusive end offset. smb2_lock() currently sets
fl_end to start + length and consequently locks one extra byte for every
nonzero-length request.
Translate nonzero lengths to start + length - 1 and reject ranges that
cannot be represented by loff_t instead of silently truncating them at
OFFSET_MAX. Track zero-length locks from the request length so one-byte
ranges are not mistaken for zero-length locks after endpoint conversion.
