Nick Terrell 90ed718d6a zstd: Fix array-index-out-of-bounds UBSAN warning
[ Upstream commit 77618db346455129424fadbbaec596a09feaf3bb ]

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.
