Prefix ext2 member variables with m_ and initialise all POD members 

To make it clear they are all member variables.  Add missing
m_fs_block_size POD (Plain Old Data) member to the constructor
initialisation list so that it's never uninitialised.  And stop
unnecessarily assigning constant false to m_force_auto_64bit in
get_filesystem_support() because it is already initialised to false by
the constructor.
