w1: ds2438: remove redundant initialization of variable crc

Browse Source 
Variable crc is being initialized with a value that is never read,
it is being re-assigned later on. The initialization is redundant
and can be removed.

Cleans up clang scan build warning:
warning: Value stored to 'crc' is never read [deadcode.DeadStores]
