branch.c: delete size check of newly tracked branch names

Since commit 6f084a56 the length of a newly tracked branch name was limited
to 1019 = 1024 - 7 - 7 - 1 characters, a bound derived by having to store
this name in a char[1024] called key with two strings of length at most 7
and a '\0' character.

This was no longer necessary as of commit a9f2c136, which uses a strbuf
(documented in Documentation/technical/api-strbuf.txt) to store this value.

Remove this unneeded check to allow branch names longer than 1019
characters.
