bcachefs: remove redundant initializations of variables start_offset and end_offset

The variables start_offset and end_offset are being initialized with
values that are never read, they being re-assigned later on. The
initializations are redundant and can be removed.

Cleans up clang-scan build warnings:
fs/bcachefs/fs-io.c:243:11: warning: Value stored to 'start_offset' during
its initialization is never read [deadcode.DeadStores]
fs/bcachefs/fs-io.c:244:11: warning: Value stored to 'end_offset' during
its initialization is never read [deadcode.DeadStores]
