Subject: [PATCH] Fix security vulnerability of non-dynamic permission removal
The original removePermission() code in PermissionManagerService
missed a logical negation operator when handling non-dynamic
permissions, causing both
testPermissionPermission_nonDynamicPermission_permissionUnchanged and
testRemovePermission_dynamicPermission_permissionRemoved tests in
DynamicPermissionsTest to fail.
The corresponding test DynamicPermissionsTest is also updated in the
other CL: ag/27073864
Bug: 321711213
Test: DynamicPermissionsTest on sc-dev and tm-dev locally
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:35d77a77feef62dc108f6478cb9228cc6044f70d)
