Christoph Hellwig be9eee2e8b smbfs: use dget_parent
Use dget_parent instead of opencoding it.  This simplifies the code, but
more importanly prepares for the more complicated locking for a parent
dget in the dcache scale patch series.

Note that the d_time assignment in smb_renew_times moves out of d_lock,
but it's a single atomic 32-bit value, and that's what other sites
setting it do already.
