Subject: perf symbols: Check return value of filename__read_debuglink()
X-Git-Tag: v3.15-rc1~181^2~9^2~1

perf symbols: Check return value of filename__read_debuglink()

When dso__read_binary_type_filename() called, it doesn't check the
return value of filename__read_debuglink() so that it'll try to open the
debuglink file even if it doesn't exist.

Also fix return value of the filename__read_debuglink() as it always
return -1 regardless of the result.
