[PATCH] mm: vmalloc: remove redundant asignmnet in unmap_kernel_range_noflush()

[Mike Rapoport]

From: Mike Rapoport <r...@linux.ibm.com>

'addr' is set to 'start' and then a few lines afterwards 'start' is
set to 'addr'.
Remove the second asignment.

Fixes: 2ba3e6947aed ("mm/vmalloc: track which page-table levels were modified")
