[PATCH] ice: switch: Simplify memory allocation

[Christophe JAILLET]

'rbuf' is locale to the ice_get_initial_sw_cfg() function.
There is no point in using devm_kzalloc()/devm_kfree().

use kzalloc()/kfree() instead.

As a side effect, it also require less memory. devm_kzalloc() has a small
memory overhead, and requesting ICE_SW_CFG_MAX_BUF_LEN (i.e. 2048) bytes,
4096 are really allocated.
