CVS commit: src/sys/uvm

["Taylor R Campbell" <riastradh%netbsd.org@localhost>]

Module Name:    src
Committed By:   riastradh
Date:           Tue Apr 19 22:53:34 UTC 2022

Modified Files:
        src/sys/uvm: uvm_mmap.c

Log Message:
Revert "mmap(2): If we fail with a hint, try again without it."

This doesn't work, because uvm_mmap releases the uobj when it fails.
Should factor this more coherently, but let's just revert for now.
