Fixes two warnings reported by smatch:
drivers/media/pci/ddbridge/ddbridge-core.c:240 ddb_redirect() warn: variable dereferenced before check 'idev' (see line 238)
drivers/media/pci/ddbridge/ddbridge-core.c:240 ddb_redirect() warn: variable dereferenced before check 'pdev' (see line 238)
Fixed by moving the existing checks up before accessing members.
