Designated initializers are required when using the randstruct GCC
plugin, otherwise an error like the following is seen:
./include/linux/lzma.h:60:31: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init]
This was originally applied via 55643e469c, but was unintentionally
reverted in 483503603c.
Fixes: 483503603c ("generic: 5.15: rework pending patch")
