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

[YueHaibing]

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

drivers/target/iscsi/cxgbit/cxgbit_ddp.c: In function 'cxgbit_ddp_init':
drivers/target/iscsi/cxgbit/cxgbit_ddp.c:303:15: 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")
