mm/nodemask: correctly describe nodemask operation return types

Commit 0dfe54071d7c8 ("nodemask: Fix return values to be unsigned")
changed a number of nodemask operations that used to return int to
returning a bool instead.  However, it did not update the comment block
that described these functions, leaving the documentation incorrect.

Fix the comment block to accurately describe the functions.  Also fix a
typo (unsigend --> unsigned), and fix a callsite in mempolicy.c that did
not get updated during the conversion.

No functional changes intended; changes are purely cosmetic.
