Clang warns:
drivers/net/wireless/ath/ath11k/wmi.c:1827:23: warning: implicit
conversion from enumeration type 'enum wmi_scan_priority' to different
enumeration type 'enum scan_priority' [-Wenum-conversion]
arg->scan_priority = WMI_SCAN_PRIORITY_LOW;
~ ^~~~~~~~~~~~~~~~~~~~~
1 warning generated.
wmi_scan_priority and scan_priority have the same values but the wmi one
has WMI prefixed to the names. Since that enum is already being used,
get rid of scan_priority and switch its one use to wmi_scan_priority to
fix this warning.

Further, it looks like the member `scan_priority` in `struct
wmi_start_scan_arg` and `struct wmi_start_scan_cmd` should probably
use `enum wmi_scan_priority`, rather than `u32`. Also, I don't know
if the more concisely named enum is preferable? Either way, thanks
for the patch.

struct wmi_start_scan_cmd is sent to firmware and that's why it has u32
to make sure that the size is exactly 32 bits.

I didn't get this comment.

Given two enums with the same values:
enum scan_priority
enum wmi_scan_priority
wouldn't you prefer to type wmi_ a few times less? Doesn't really
matter, but that was the point I was making.

Ah, now I got it :) This enum is part of firmware interface (WMI) so
yes, I prefer to use the wmi_ prefix to make that obvious.
