Subject: [PATCH -next] scsi: cxgb4i: remove set but not used variable 'ppmax'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:2076:15:
 warning: variable ppmax set but not used [-Wunused-but-set-variable]
drivers/target/iscsi/cxgbit/cxgbit_ddp.c:300:15:
 warning: variable ppmax set but not used [-Wunused-but-set-variable]

It is not used since commit a248384e6420 ("cxgb4/libcxgb/
cxgb4i/cxgbit: enable eDRAM page pods for iSCSI")
