net/mlx5: remove redundant clear_bit

Browse source 
When shutdown or remove callbacks are called the driver sets the flag
MLX5_BREAK_FW_WAIT, to stop waiting for FW as teardown was called. There
is no need to clear the bit as once shutdown or remove were called as
there is no way back, the driver is going down. Furthermore, if not
cleared the flag can be used also in other loops where we may wait while
teardown was already called.

Use test_bit() instead of test_and_clear_bit() as there is no need to
clear the flag.
