[PATCH 1/1] git-p4: fix `sync --verbose` traceback due to 'fileSize'

[Andrey Mazo <amazo@checkvideo.com>]

Perforce server 2007.2 (and maybe others) doesn't return "fileSize"
attribute in its reply to `p4 -G print` command.
This causes the following traceback when running `git p4 sync --verbose`:
"""
    Traceback (most recent call last):
      File "/usr/libexec/git-core/git-p4", line 3839, in <module>
	main()
      File "/usr/libexec/git-core/git-p4", line 3833, in main
	if not cmd.run(args):
      File "/usr/libexec/git-core/git-p4", line 3567, in run
	self.importChanges(changes)
      File "/usr/libexec/git-core/git-p4", line 3233, in importChanges
	self.commit(description, filesForCommit, branch, parent)
      File "/usr/libexec/git-core/git-p4", line 2855, in commit
	self.streamP4Files(files)
      File "/usr/libexec/git-core/git-p4", line 2747, in streamP4Files
	cb=streamP4FilesCbSelf)
      File "/usr/libexec/git-core/git-p4", line 552, in p4CmdList
	cb(entry)
      File "/usr/libexec/git-core/git-p4", line 2741, in streamP4FilesCbSelf
	self.streamP4FilesCb(entry)
      File "/usr/libexec/git-core/git-p4", line 2689, in streamP4FilesCb
	self.streamOneP4File(self.stream_file, self.stream_contents)
      File "/usr/libexec/git-core/git-p4", line 2566, in streamOneP4File
	size = int(self.stream_file['fileSize'])
    KeyError: 'fileSize'
"""

Fix this by omitting the file size information from the verbose print out.
Also, don't use "self.stream_file" directly,
but rather use passed in "file" argument.
(which point to the same "self.stream_file" for all existing callers)
