bnxt_en: read EEPROM A2h address using page 0

Browse Source 
[ Upstream commit 4260330b32 ]

The module eeprom address range returned by bnxt_get_module_eeprom()
should be 256 bytes of A0h address space, the lower half of the A2h
address space, and page 0 for the upper half of the A2h address space.

Fix the firmware call by passing page_number 0 for the A2h slave address
space.

Fixes: 42ee18fe4c ("bnxt_en: Add Support for ETHTOOL_GMODULEINFO and ETHTOOL_GMODULEEEPRO")
