Handle NotImplementedError exception while changing optoe write max

[mihirpat1]

What I did

For platforms which do not implement get_eeprom_path API, NotImplementedError will be returned when the user downloads CDB firmware through "sfputil firmware download <port> <fw_path>" CLI.
We need to handle such case and allow FW download to proceed since the corresponding platform may not support Optoe driver or may not have get_eeprom_path not implemented.

How I did it

Handling NotImplementedError exception now while calling set_optoe_write_max API to allow FW download.

How to verify it

The "sfputil firmware download <fw_path>" CLI was verified successfully in the following scenarios

1. When get_eeprom_path API is implemented
2. When get_eeprom_path API is not implemented

Previous command output (if the output of a command-line utility has changed)

Error seen while initiating FW download when get_eeprom_path is not defined
