mmc: wbsd: remove redundant assignment to variable id

The variable id 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:
drivers/mmc/host/wbsd.c:1287:4: warning: Value stored to 'id'
is never read [deadcode.DeadStores]
