eCryptfs: remove unnecessary page decrypt call
The page decrypt calls in ecryptfs_write() are both pointless and buggy. Pointless because ecryptfs_get_locked_page() has already brought the page up to date, and buggy because prior mmap writes will just be blown away by the decrypt call. This patch also removes the declaration of a now-nonexistent function ecryptfs_write_zeros(). Thanks to Eric Sandeen and David Kleikamp for helping to track this down. Eric said: fsx w/ mmap dies quickly ( < 100 ops) without this, and survives nicely (to millions of ops+) with it in place.
