[PATCH] libtracefs: Remove unused variable mode in tracefs_cpu_alloc_fd()

[Steven Rostedt <rostedt@goodmis.org>]

From: Steven Rostedt <rostedt@goodmis.org>

When tracefs_cpu_alloc_fd() was introduced, it broke up
-tracefs_cpu_open() to use parts in multiple functions. As
tracefs_cpu_alloc_fd() was created from -tracefs_cpu_open(), it had the
mode variable from that function, but it never used it.
Remove the unuesd mode variable.

Fixes: da88fcef46b46 ("libtracefs: Add tracefs_cpu_alloc_fd() and tracefs_cpu_free_fd()")
