object-store: avoid extra ';' from KHASH_INIT

cf2dc1c (speed up alt_odb_usable() with many alternates, 2021-07-07)
introduces a KHASH_INIT invocation with a trailing ';', which while
commonly expected will trigger warnings with pedantic on both
clang[-Wextra-semi] and gcc[-Wpedantic], because that macro has already
a semicolon and is meant to be invoked without one.

while fixing the macro would be a worthy solution (specially considering
this is a common recurring problem), remove the extra ';' for now to
minimize churn.
