Hristo Venev a5a8fc0679 be2net: Fix buffer overflow in be_get_module_eeprom
[ Upstream commit d7241f679a59cfe27f92cb5c6272cb429fb1f7ec ]

be_cmd_read_port_transceiver_data assumes that it is given a buffer that
is at least PAGE_DATA_LEN long, or twice that if the module supports SFF
8472. However, this is not always the case.

Fix this by passing the desired offset and length to
be_cmd_read_port_transceiver_data so that we only copy the bytes once.

Fixes: e36edd9d26cf ("be2net: add ethtool "-m" option support")
