ShellPkg/TftpDynamicCommand: Clarify the retry count option in command.

[-c <retry count>] is to define the number of times to transmit request
packets and wait for a response. The default value is 6. But it doesn't
specify the behavior of zero value. Here, The patch is to clear that:
Set to zero also means to use the default value.
