[PATCH] packfile: make `close_pack_revindex()` static

[Taylor Blau <me@ttaylorr.com>]

Since its definition in 2f4ba2a867 (packfile: prepare for the existence
of '*.rev' files, 2021-01-25), the only caller of
`close_pack_revindex()` was within packfile.c.

Thus there is no need for this to be exposed via packfile.h, and instead
can remain static within packfile.c's compilation unit. While we're
here, move the function's opening brace onto its own line.

Noticed by Ramsay in a separate thread[1], because the two
style/organization fixes here were propagated into the new cruft pack
code.
