accel/habanalabs/goya: remove redundant assignment to pointer 'input'

The pointer input is assigned a value that is not read, it is
being re-assigned again later with the same value. Resolve this
by moving the declaration to input into the if block.

Cleans up clang scan build warning:
warning: Value stored to 'input' during its initialization is never
read [deadcode.DeadStores]
