hdt: Move ~162K byte data object from the stack to the bss
A struct s_hardware is far too large to be placed onto the stack and was causing us run past the end of the allocated stack and overwrite the diskcache, which resulted in apparent file system corruption. Move this hefty object into the bss. Cc: Erwan Velu <erwanaliasr1@gmail.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
