Opens on lower dentry objects happen in several places in eCryptfs, and they
all involve the same steps (dget, mntget, dentry_open). This patch
consolidates the lower open events into a single function call.

eCryptfs is a stacked cryptographic filesystem for Linux. It is derived from
Erez Zadok's Cryptfs, implemented through the FiST framework for generating
stacked filesystems. eCryptfs extends Cryptfs to provide advanced key
management and policy features. eCryptfs stores cryptographic metadata in the
header of each file written, so that encrypted files can be copied between
hosts; the file will be decryptable with the proper key, and there is no need
to keep track of any additional information aside from what is already in the
encrypted file itself.
