[PATCH] PCI: endpoint: remove redundant initialization of pointer dev

[PATCH] PCI: endpoint: remove redundant initialization of pointer dev

[Colin King]

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

The pointer dev is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.
