[PATCH v3 19/25] try_merge_strategy(): remove redundant lock_file allocation

By the time the "if" block is entered, the lock_file instance from the
main function block is no longer in use, so re-use that one instead of
allocating a second one.

Note that the "lock" variable in the "if" block shadowed the "lock"
variable at function scope, so the only change needed is to remove the
inner definition.
