 btsdio_remove due to race condition

Hi Greg,

This change is required to fix kernel CVE: CVE-2023-1989 which is reported in v6.1 kernel version. It is fixed in upstream starting from v6.3 kernel version and required to fix in 6.1 kernel version as well so we have backported this from v6.3 kernel version to v6.1 and I have sent this patch for review and merging.

Regards,
Deepak
