Use the disk currently in use by SONiC for the 'show platform ssdhealth' command.

What I did

Due to a USB flash drive being plugged in, the SONiC command 'show platform ssdhealth' does not display correctly.

admin@sonic:~$ show platform ssdhealth
[Error] Cannot read device /dev/sda
Device Model : N/A
Health : N/A
Temperature : N/A

dmesg log :

How I did it

Use the SSD disk currently in use by SONiC as the default argument for the 'ssdutil' command.

How to verify it

1. Plugging in a USB flash drive.
2. "show platform ssdhealth"

admin@sonic:~$ show platform ssdhealth
Device Model : MPT160-M8240GCB5ACT-E132
Health       : 100.0%
Temperature  : 27.0C
