transport-helper: remove name parameter

Commit 266f1fdfa (transport-helper: be quiet on read errors from
helpers, 2013-06-21) removed a call to 'die()' which printed the name of
the remote helper passed in to the 'recvline_fh()' function using the
'name' parameter.  Once the call to 'die()' was removed the parameter
was no longer necessary but wasn't removed.  Clean up 'recvline_fh()'
parameter list by removing the 'name' parameter.
