Subject: [PATCH 5.14 294/432] net/mlx5: Fix variable type to match 64bit

From: Eran Ben Elisha <eranbe@...dia.com>

[ Upstream commit 979aa51967add26b37f9d77e01729d44a2da8e5f ]

Fix the following smatch warning:
wait_func_handle_exec_timeout() warn: should '1 << ent->idx' be a 64 bit type?

Use 1ULL, to have a 64 bit type variable.
