[PATCH 1/2] btrfs-progs: receive: get rid of unnecessary strdup()

[Omar Sandoval <osandov@xxxxxxxxxxx>]

From: Omar Sandoval <osandov@xxxxxx>

In process_clone(), we're not checking the return value of strdup().
But, there's no reason to strdup() in the first place: we just pass the
path into path_cat_out(). Get rid of the strdup().

Fixes: f1c24cd80dfd ("Btrfs-progs: add btrfs send/receive commands")
