Subject: bpf: Remove redundant initialization of variable allow
Patch-mainline: v5.15-rc1
Git-commit: 8cacfc85b615cc0bae01241593c4b25da6570efc
References: jsc#PED-1377

The variable allow is being initialized with a value that is never read, it
is being updated later on. The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
