[PATCH] mempolicy: clean up minor dead code in queue_pages_test_walk()

[PATCH] mempolicy: clean up minor dead code in queue_pages_test_walk()

[Lukas Bulwahn]

Commit 2cafb582173f ("mempolicy: remove confusing MPOL_MF_LAZY dead code")
removes MPOL_MF_LAZY handling in queue_pages_test_walk(), and with that,
there is no effective use of the local variable endvma in that function
remaining.

Remove the local variable endvma and its dead code. No functional change.

This issue was identified with clang-analyzer's dead stores analysis.
