devlink: Fix inconsistency between command input and output

In devlink health show command the reporter's name parameter is called
reporter, but in the output the reporter's name is referred to as name

Before this patch:
$ devlink health show pci/0000:04:00.0 reporter tx
pci/0000:04:00.0:
   name tx
     state healthy error 0 recover 0 grace_period 500 auto_recover true

After this patch:
$ devlink health show pci/0000:04:00.0 reporter tx
pci/0000:04:00.0:
   reporter tx
     state healthy error 0 recover 0 grace_period 500 auto_recover true
