[PATCH v2] ALSA: maestro3: using vmalloc_array() to handle the code

[tanze <tanze@kylinos.cn>]

Change array_size() to vmalloc_array(), due to vmalloc_array()
being optimized better, using fewer instructions, and handles
overflow more concisely.

Hi, Philipp Stanner,

Thank you for your suggestions.
I have made revisions according to your requirements.

Regarding the issue of my full name, thank you for your 
attention to detail. Since I am in China, I use the name 
"tanze" on many occasions, and the code I previously submitted 
to the upstream community was also under this name.
