soc/intel/cmn/blk.cse: Fix check condition in store_cse_rw_fw_version()

The return value of cse_get_bp_info() is an enum integer, where zero
means success and non-zero means failure. The function
store_cse_rw_fw_version() calls the function cse_get_bp_info() and
validates the return value as a boolean causing prematurely returns of
the parent API even if cse_get_bp_info() is successful.

This patch corrects this logical error by returning only if
cse_get_bp_info() fails.

TEST=Build and boot google/nivviks and verify that the ISH version info
command is only being sent during cold boot.
