mtd: chips: remove redundant assignment to variable timeo

In two functions the variable timeo is being initialized with a value
that is never read, it is being re-assigned later on. The initializations
are redundant and can be removed.

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