Subject: [PATCH] mwlwifi: replace get/set_fs() calls
Since kernel 5.9 the get/set_fs() call implementation have started to get
dropped from individual architectures, ARM64 one got dropped in 5.11.
Replace the get/set_fs() calls with force_uaccess_begin/end() to allow
compiling on newer kernels.
There is no need to add kernel version checks as the replacement functions
are available since kernel 5.9.
