Volker Lendecke d4b7ff9ede cifs: Fix uninitialized memory read for smb311 posix symlink create 
commit a152d05ae4 upstream.

If smb311 posix is enabled, we send the intended mode for file
creation in the posix create context. Instead of using what's there on
the stack, create the mfsymlink file with 0644.

Fixes: ce558b0e17 ("smb3: Add posix create context for smb3.11 posix mounts")
