btrfs: discard: Use the correct style for SPDX License Identifier

This patch corrects the SPDX License Identifier style in header file
related to Btrfs File System support.  For C header files
Documentation/process/license-rules.rst mandates C-like comments
(opposed to C source files where C++ style should be used).
