[PATCH 08/22] firmware: arm_scmi: Remove unneeded NULL termination of clk name

The string array 'name' inside struct scmi_clock_info holds the clock name
which was successfully retrieved by querying the SCMI platform, unless the
related underlying SCMI command failed.

Anyway, such scmi_clock_info structure is allocated using devm_kcalloc()
which in turn internally appends a __GFP_ZERO flag to its invocation:
as a consequence the string 'name' field does not need to be zeroed when
we fail to get the clock name via SCMI, it is already NULL terminated.

Remove unneeded explicit NULL termination.
