[PATCH] SCSI: bnx2i: requires MMU

[Randy Dunlap]

The SCSI_BNX2_ISCSI kconfig symbol selects CNIC and CNIC selects UIO,
which depends on MMU.
Since 'select' does not follow dependency chains, add the same MMU
dependency to SCSI_BNX2_ISCSI.

Quietens this kconfig warning:

WARNING: unmet direct dependencies detected for CNIC
  Depends on [n]: NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_BROADCOM [=y] && PCI [=y] && (IPV6 [=m] || IPV6 [=m]=n) && MMU [=n]
  Selected by [m]:
  - SCSI_BNX2_ISCSI [=m] && SCSI_LOWLEVEL [=y] && SCSI [=y] && NET [=y] && PCI [=y] && (IPV6 [=m] || IPV6 [=m]=n)

Fixes: cf4e6363859d ("[SCSI] bnx2i: Add bnx2i iSCSI driver.")
