sfputil: skip displaying the values that are not supported.

[vvolam]

What I did

Skip displaying the fields which are unsupported for CMIS specific transceivers.

How I did it

Skip the key with "N/A" value in convert_sfp_info_to_output_string()

How to verify it

Verified 'show interfaces transceiver info' and 'sfputil show eeprom -p' outputs on an Arista testbed.

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

sfputil show eeprom -d -p Ethernet0
