description:
uvm_page_unbusy should skip PGO_DONTCARE page; e.g., locked pgo_getpages
request may contain PGO_DONTCARE and nfs_getpages may unbusy them on error.

Fix is provided in PR#20028 by YAMAMOTO Takashi.  (and same one is approved
by chuq while ago in private mail).  It was my fault to forget to commit.
