[PATCH] hfsplus: rework processing of return value of bio_alloc() in hfsplus_submit_bio()

[Vyacheslav Dubeyko <slava@dubeyko.com>]

Hi,

This patch adds logic of checking return value of bio_alloc() in hfsplus_submit_bio(). In the case of NULL the hfsplus_submit_bio() returns -EIO.

With the best regards,
Vyacheslav Dubeyko.
