staging: vt6655: remove redundant assignment to variable byData

Variable byData is being assigned a value that is never read, it is
being re-assigned later on. The assignment is redundant and can be
removed.

Cleans up clang scan build warning:
drivers/staging/vt6655/srom.c:67:2: warning: Value stored to 'byData'
is never read [deadcode.DeadStores]
