Subject: [PATCH v2 8/8] staging: vt6655: Delete bogus check for `init_count` in AL7230

Remove an unnecessary check in `rf_write_wake_prog_syn` in `RF_AIROHA7230`
switch case. This `if` conditional will never be true as `init_count` is
equal to 19 and can't be bigger than `MISCFIFO_SYNDATASIZE - 0`, which
is equal to 21.
