cgit_print_tree(): Free curr_rev after usage

Fixes following memory leak seen with "PATH_INFO=/cgit/tree/":

    ==15715== 7 bytes in 1 blocks are definitely lost in loss record 4 of 51
    ==15715==    at 0x4C2C04B: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
    ==15715==    by 0x56F2DF1: strdup (in /usr/lib/libc-2.17.so)
    ==15715==    by 0x46CAA8: xstrdup (wrapper.c:35)
