Subject: [PATCH] staging: erofs: clean up initialization of pointer de

From: Colin Ian King <colin.king@...onical.com>

Currently pointer de is being initialized with a value that is
never read and a few statements later de is being re-assigned. Clean
this up by ininitialzing de and removing the re-assignment.

Addresses-Coverity: ("Unused value")
