tools: hv: fcopy: set 'error' in case an unknown operation was requested

vittyvk · gregkh · commit c2d68afba86d · 2018-09-30T08:49:55.000-07:00
'error' variable is left uninitialized in case we see an unknown operation.
As we don't immediately return and proceed to pwrite() we need to set it
to something, HV_E_FAIL sounds good enough.
