mm: remove redundant check about FAULT_FLAG_ALLOW_RETRY bit

Since commit 4064b9827063 ("mm: allow VM_FAULT_RETRY for multiple
times") allowed VM_FAULT_RETRY for multiple times, the
FAULT_FLAG_ALLOW_RETRY bit of fault_flag will not be changed in the page
fault path, so the following check is no longer needed:

flags & FAULT_FLAG_ALLOW_RETRY

So just remove it.

[akpm@linux-foundation.org: coding style fixes]
