pack-bitmap.c: do not ignore error when opening a bitmap file
Calls to git_open() to open the pack bitmap file and
multi-pack bitmap file do not report any error when they
fail. These files are optional and it is not an error if
open failed due to ENOENT, but we shouldn't be ignoring
other kinds of errors.
