[PATCH 1/4] object-file: reread object with exact same args

[Jonathan Tan <jonathantanmy@google.com>]

When an object in do_oid_object_info_extended() is found in a packfile,
but corrupt, that packfile entry is marked as bad and the read is
retried. Currently, this is done by invoking the function again but with
the replace target of the object and with no flags.

This currently works, but will be clumsy when a later patch modifies
this function to also return the "real" object being read (that is, the
replace target). It does not make sense to pass a pointer in order to
receive this information when no replace lookups are requested, which is
exactly what the reinvocation does.

Therefore, change this reinvocation to pass exactly the arguments which
were originally passed. This also makes us forwards compatible with
future flags that may change the behavior of this function. This does
slow down the case when packfile corruption is detected, but that is
expected to be a very rare case.
