bcachefs: Fix unnecessary read amplificaiton when allocating ec stripes
When allocating an erasure coding stripe, bcachefs will always reuse any
partial stripes before reserving a new stripe. This causes unnecessary
read amplification when preparing a stripe for writing. This patch changes
bcachefs to always reserve new stripes first, only relying on stripe reuse
when copygc needs more time to empty buckets from existing stripes.
