[PATCH] perf tools: Initialize perf_data_file fd field

[JÃrÃmie Galarneau]

Building the perf CTF converter fails with gcc 4.8.4
on Ubuntu 14.04 with the following error:

error: missing initializer for field âfdâ of âstruct perf_data_fileâ
[-Werror=missing-field-initializers]

Per 4b838b0d and the ensuing discussion on the mailing
list, it appears that this affects other distributions
and gcc versions.
