media: anysee: Fix and remove outdated comment

anysee driver was transformed to use usbv2 years ago. The comments in
anysee_ctrl_msg() still are referencing the old interfaces where msleep()
was used. The v2 interfaces also changed over the years and with commit
1162c7b383a6 ("[media] dvb_usb_v2: refactor dvb_usbv2_generic_rw()") the
usage of msleep() was gone anyway.

Remove FIXME comment and update also comment before call to
dvb_usbv2_generic_rw_locked().
