Jeff Cody 113fe792fd block/nfs: fix mutex assertion in nfs_file_close() 
Commit c096358e74 introduced assertion
checks for when qemu_mutex() functions are called without the
corresponding qemu_mutex_init() having initialized the mutex.

This uncovered a latent bug in qemu's nfs driver - in
nfs_client_close(), the NFSClient structure is overwritten with zeros,
prior to the mutex being destroyed.

Go ahead and destroy the mutex in nfs_client_close(), and change where
we call qemu_mutex_init() so that it is correctly balanced.

There are also a couple of memory leaks obscured by the memset, so this
fixes those as well.

Finally, we should be able to get rid of the memset(), as it isn't
necessary.
