[PATCH v2 06/29] be2iscsi: Fix release of DHCP IP in static mode

[Jitendra Bhivare <jitendra.bhivare@xxxxxxxxxxxx>]

If BOOTPROTO is changed to static, the DHCP IP address should be released.
All cases are being handled mgmt_set_ip and mgmt_static_ip_modify.

Rearrange IFACE APIs to:
beiscsi_if_clr_ip
beiscsi_if_set_ip
beiscsi_if_en_static
beiscsi_if_en_dhcp

This simplifies release of DHCP IP when BOOTPROTO is set to static.
