hugetlb: move vm_fault declaration to the top of hugetlb_fault()

Browse source

hugetlb_fault() currently defines a vm_fault to pass to the generic
handle_userfault() function.  We can move this definition to the top of
hugetlb_fault() so that it can be used throughout the rest of the hugetlb
fault path.

This will help cleanup a number of excess variables and function arguments
throughout the stack.  Also, since vm_fault already has space to store the
page offset, use that instead and get rid of idx.
