builtin/checkout: clear pending objects after diffing
add_pending_object() populates rev.pending, we need to take care of clearing it once we're done. This code is run close to the end of a checkout, therefore this leak seems like it would have very little impact. See also LSAN output from t0020 below: Direct leak of 2048 byte(s) in 1 object(s) allocated from: #0 0x49ab79 in realloc ../projects/compiler-rt/lib/asan/asan_malloc_linux.cpp:164:3 #1 0x9acc46 in xrealloc wrapper.c:126:8 #2 0x83e3a3 in add_object_array_with_path object.c:337:3 #3 0x8f672a in add_pending_object_with_path revision.c:329:2 #4 0x8eaeab in add_pending_object_with_mode revision.c:336:2 #5 0x8eae9d in add_pending_object revision.c:342:2 #6 0x5154a0 in show_local_changes builtin/checkout.c:602:2 #7 0x513b00 in merge_working_tree builtin/checkout.c:979:3 #8 0x512cb3 in switch_branches builtin/checkout.c:1242:9 #9 0x50f8de in checkout_branch builtin/checkout.c:1646:9 #10 0x50ba12 in checkout_main builtin/checkout.c:2003:9 #11 0x5086c0 in cmd_checkout builtin/checkout.c:2055:8 #12 0x4cd91d in run_builtin git.c:467:11 #13 0x4cb5f3 in handle_builtin git.c:719:3 #14 0x4ccf47 in run_argv git.c:808:4 #15 0x4caf49 in cmd_main git.c:939:19 #16 0x69e43e in main common-main.c:52:11 #17 0x7f5dd1d50349 in __libc_start_main (/lib64/libc.so.6+0x24349) SUMMARY: AddressSanitizer: 2048 byte(s) leaked in 1 allocation(s).
