treewide: remove unnecessary unnamed structs/unions

Browse Source 
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch removes unnamed struct/union fields that can be easily
expressed in a C99-compatible way.

Here is a summary of structs/unions removed.

struct vhm_request:

    union {
        uint32_t type;                  uint32_t type;
        int32_t reserved0[16];    =>    int32_t reserved0[15];
    };

struct vhm_request_buffer:

    struct vhm_request_buffer {
        union {                         union vhm_request_buffer {
            struct vhm_request ...; =>        struct vhm_request ...;
            int8_t reserved[4096];            int8_t reserved[4096];
        }                               }
    }
