xfrm: policy: remove set but not used variable 'priority'

Fixes gcc '-Wunused-but-set-variable' warning:

net/xfrm/xfrm_policy.c: In function 'xfrm_policy_lookup_bytype':
net/xfrm/xfrm_policy.c:2079:6: warning:
 variable 'priority' set but not used [-Wunused-but-set-variable]

It not used since commit 6be3b0db6db8 ("xfrm: policy: add inexact policy
search tree infrastructure")
