HID: intel_ish-hid: tx_buf memory leak on probe/remove
ish_dev_init() allocates 512*176 bytes memory for tx_buf and stores it at
&dev->wr_free_list_head.link list on ish_probe().
But there is no deallocation of this memory in ish_remove() and in
ish_probe() error path.
So current intel-ish-ipc provides 88 KB memory leak for each
probe/release.
The patch replaces kzalloc allocation by devm_kzalloc and removes
ishtp_device *dev deallocation by kfree.
Found by Linux Driver Verification project (linuxtesting.org).
