LU-16118 build: Workaround __write_overflow_field errors

Linux commit v5.17-rc3-1-gf68f2ff91512
   fortify: Detect struct member overflows in memcpy() at compile-time

memcpy and memset of collections of struct members
will trigger:

error: call to ‘__write_overflow_field’ declared with attribute
   warning: detected write beyond size of field (1st parameter);
   maybe use struct_group()?
   [-Werror] __write_overflow_field(p_size_field, size);
