fs/fuse: Remove unneeded kaddr parameter

Browse Source 
fuse_dax_mem_range_init() does not need the address or the pfn of the
memory requested in dax_direct_access().  It is only calling direct
access to get the number of pages.

Remove the unused variables and stop requesting the kaddr and pfn from
dax_direct_access().
