[PATCH] firmware: arm_scmi: Do not use !! on boolean when setting msg->flags

[Sudeep Holla]

Both pc->async_powercap_cap_set and ignore_dresp are already boolean.
Use of !! on them is obviously dubious.

Sparse reports:
drivers/firmware/arm_scmi/powercap.c:363:17: warning: dubious: x & !y
drivers/firmware/arm_scmi/powercap.c:363:17: warning: dubious: x & !y

Remove the unnecessary !! and get rid of the warning.
