ice: Fix recipe read procedure

Browse Source 
[ Upstream commit 19abb9c2b900bad59e0a9818d6c83bb4cc875437 ]

When ice driver reads recipes from firmware information about
need_pass_l2 and allow_pass_l2 flags is not stored correctly.
Those flags are stored as one bit each in ice_sw_recipe structure.
Because of that, the result of checking a flag has to be casted to bool.
Note that the need_pass_l2 flag currently works correctly, because
it's stored in the first bit.

Fixes: bccd9bce29e0 ("ice: Add guard rule when creating FDB in switchdev")
