Zstd used an array of length 1 to mean a flexible array for C89 compatibility. Switch to a C99 flexible array to fix the UBSAN warning. Tested locally by booting the kernel and writing to and reading from a BtrFS filesystem with zstd compression enabled. I was unable to reproduce the issue before the fix, however it is a trivial change.
