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

[YueHaibing]

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

drivers/scsi/cxgbi/cxgb4i/cxgb4i.c: In function 'cxgb4i_ddp_init':
drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:2072:15: warning:
 variable 'ppmax' set but not used [-Wunused-but-set-variable]

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