[PATCH] v9fs: handle kthread_create failure, minor bugfixes
- remove unnecessary -ENOMEM assignments - return correct value when buf_check_size for second time in a buffer - handle failures when create_workqueue and kthread_create are called - use kzalloc instead of kmalloc/memset 0 - v9fs_str_copy and v9fs_str_compare were buggy, were used only in one place, correct the logic and move it to the place it is used.
