[RFC/PATCHv0 1/4] fast-import.c:do_change_note_fanout(): Remove unneeded local var 't'

[Johan Herland <johan@herland.net>]

The struct tree_content *t variable was used as a shorthand for the
given root->tree, but it was only used in the first two lines of the for
loop, so the shorthand itself does not add much value. Furthermore,
since the for loop body might end up reallocating root->tree we had to
reinitialize t at the end of the for loop body, which is ugly and brittle.

Simply use root->tree directly instead, and remote the t shorthand.
