perf pmu: Fix misleadingly indented assignment (whitespace)

[ Upstream commit d85ce830eef6c10d1e9617172dea4681f02b8424 ]

One line in perf_pmu__parse_unit() is indented wrongly, leading to a
warning (=> error) from gcc 6:

  util/pmu.c:156:3: error: statement is indented as if it were guarded by... [-Werror=misleading-indentation]

    sret = read(fd, alias->unit, UNIT_MAX_LEN);
    ^~~~

  util/pmu.c:153:2: note: ...this 'if' clause, but it is not
    if (fd == -1)
    ^~
