Description:

I ran pacman -Syu under 5.15.10, but soon I kept getting Microcode SW error (see attachment IWL_Error_Log_Dump_5.15.10.log, output of `journalctl -b -1|grep -E 'iwlwifi|wlan0|iwd'`).

I thought it might be caused by incomplete upgrade, and then restarted to 5.15.11, but got `Direct firmware load for iwlwifi-cc-a0-66.ucode failed with error -2` (see attachment IWL_Error_Log_Dump_5.15.11.log, output of `journalctl -b 0|grep -E 'iwlwifi|wlan0|iwd'`).

In either case, the card became unable to associate with access points.

Suspicious logs from IWL_Error_Log_Dump_5.15.11.log:
`kernel: iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-cc-a0-6{6,5,4}.ucode failed with error -2`,
`iwd[682]: NEW_INTERFACE failed: Too many open files in system`,
`kernel: iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x0.`,
`kernel: iwlwifi 0000:02:00.0: Loaded firmware version: 63.c04f3485.0 cc-a0-63.ucode`,
`kernel: iwlwifi 0000:02:00.0: 0x00000071 | NMI_INTERRUPT_UMAC_FATAL`

Steps to reproduce:
