Subject: [PATCH][next] PCI: brcmstb: fix a missing if statement on a return error check

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

The error return ret is not being check with an if statement and
currently the code always returns leaving the following code as
dead code. Fix this by adding in the missing if statement.

Addresses-Coverity: ("Structurally dead code")
Fixes: ad3d29c77e1e ("PCI: brcmstb: Add control of rescal reset")
