[CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to access 

unaligned structures coming in off the wire

gcc on arm processors generates very odd code with pragma pack specified -
although it does pack the structures in some sense - it does not allow you
to access unaligned elements in nested structures at the right offset as other
architectures do.  Oddly enough though, specifying the structures as packed
the long way - one by one with the packed attribute does work.  Rather than
fighting over whether this is a gcc bug or some obscure side effect
of pragma pack, it is easier to do what most (all but 96 other places in
the kernel) do - and replace pragma pack with dozens of attribute(packed)
structure qualifiers.  Much more verbose ... but at least it works.
