[PATCH] net: dsa: sja1105: Remove unneeded cast in sja1105_crc32()

sja1105_unpack() takes a "const void *buf" as its first parameter, so
there is no need to cast away the "const" of the "buf" variable before
calling it.

Drop the cast, as it prevents the compiler performing some checks.

Compile-tested only.

BTW, sja1105_packing() and packing() are really bad APIs, as the input
pointer parameters cannot be const due to the direction depending on
"op".  This means the compiler cannot do const checks.  Worse, callers
are required to cast away constness to prevent the compiler from
issueing warnings.  Please don't do this!
