fs/squashfs: Add init and clean-up functions to decompression
Add sqfs_decompressor_init() and sqfs_decompressor_cleanup(). These
functions are called respectively in sqfs_probe() and sqfs_close(). For
now, only ZSTD requires an initialization logic. ZSTD support will be
added in a follow-up commit.
Move squashfs_ctxt definition to sqfs_filesystem.h. This structure is
passed to sqfs_decompressor_init() and sqfs_decompressor_cleanup(), so
it can no longer be local to sqfs.c.
