[PATCH] crypto: af_alg: clean up kernel-doc warnings

[Randy Dunlap <rdunlap@infradead.org>]

- add missing struct member @wait, drop @completion
- convert function comments to kernel-doc format
- for af_alg_readable(), change comments from "writable" to "readable"

Warning: include/crypto/if_alg.h:161 struct member 'wait' not described
 in 'af_alg_ctx'
Warning: include/crypto/if_alg.h:161 Excess struct member 'completion'
 description in 'af_alg_ctx'
Warning: include/crypto/if_alg.h:187 This comment starts with '/**', but
 isn't a kernel-doc comment.
 * Size of available buffer for sending data from user space to kernel.
Warning: include/crypto/if_alg.h:202 This comment starts with '/**', but
 isn't a kernel-doc comment.
 * Can the send buffer still be written to?
Warning: include/crypto/if_alg.h:213 This comment starts with '/**', but
 isn't a kernel-doc comment.
 * Size of available buffer used by kernel for the RX user space operation.
Warning: include/crypto/if_alg.h:228 This comment starts with '/**', but
 isn't a kernel-doc comment.
 * Can the RX buffer still be written to?
