FreeBSD: Fix file descriptor leak on pool import. #15630

  1. Fix file descriptor leak on pool import. 

    Descriptor leak can be easily reproduced by doing:

	# zpool import tank
	# sysctl kern.openfiles
	# zpool export tank; zpool import tank
	# sysctl kern.openfiles

We were leaking four file descriptors on every import.

Similar leak most likely existed when using file-based VDEVs.
