gitweb.js: No need for loop in blame_incremental's handleResponse()

JavaScript is single-threaded, so there is no need for protecting
against changes to XMLHttpRequest object behind event handler back.

Therefore there is no need for loop that was here in case `xhr' got
new changes while processing current changes.  This should make code a
bit more clear.
