[PATCH -next] bcache: Add missing parameter description to bch2_bucket_alloc_trans()

[Yang Li <yang.lee@linux.alibaba.com>]

The function bch2_bucket_alloc_trans() lacked a description for the
nowait parameter in its documentation comment block. This patch adds the
missing description to ensure all parameters are properly documented.
