[PATCH 1/8] net: qualcomm: rmnet: fix struct rmnet_map_header

The C bit-fields in the first byte of the rmnet_map_header structure
are defined in the wrong order.  The first byte should be formatted
this way:
                 +------- reserved_bit
                 | +----- cd_bit
                 | |
                 v v
    +-----------+-+-+
    |  pad_len  |R|C|
    +-----------+-+-+
     7 6 5 4 3 2 1 0  <-- bit position

But the C bit-fields that define the first byte are defined this way:
    u8 pad_len:6;
    u8 reserved_bit:1;
    u8 cd_bit:1;

And although this isn't portable, I can state that when I build it
the result puts the bit-fields in the wrong location (e.g., the
cd_bit is in bit position 7, when it should be position 0).

Fix this by reordering the definitions of these struct members.
Upcoming patches will reimplement these definitions portably.
