powerpc: remove non-dependent load fsl_booke PTE_64BIT

b38fd42f

 added false dependencys
to order the load of upper and lower halfs of the pte, but only
adjusted whitespace instead of deleting the old load in the iside
handler, letting the hardware see the non-dependent load.

This patch removes the extra load.
