[PATCH] mm: add colon to fix kernel-doc markups error for check_pte

[Alex Shi <alex.shi@linux.alibaba.com>]

The function check_pte needs a correct colon for kernel-doc markup,
otherwise, gcc has the following warning for W=1,
mm/page_vma_mapped.c:86: warning: Function parameter or member 'pvmw'
not described in 'check_pte'
