Yunfeng Ye 5952dc84e2 perf kmem: Fix memory leak in compact_gfp_flags() 
[ Upstream commit 1abecfcaa7bba21c9985e0136fa49836164dd8fd ]

The memory @orig_flags is allocated by strdup(), it is freed on the
normal path, but leak to free on the error path.

Fix this by adding free(orig_flags) on the error path.

Fixes: 0e11115644 ("perf kmem: Print gfp flags in human readable string")
