        src/external/cddl/osnet/dist/uts/common/fs/zfs: zfs_rlock.c
        src/external/cddl/osnet/dist/uts/common/fs/zfs/sys: zfs_rlock.h

Log Message:
zfs: add zfs_range_lock_try

i plan to use this to fix pgdaemon deadlock issue. (PR/60004)
(thus i didn't bother to implement RL_READER.)

note: recent openzfs has a similar function. (zfs_rangelock_tryenter)
this commit ought to be reverted when/if we switch to it.
