[PATCH 2/2] block: blk-tag: Replace GFP_ATOMIC with GFP_KERNEL in init_tag_map

[Jia-Ju Bai]

After checking all possible call chains to init_tag_map here,
my tool finds that init_tag_map is never called in atomic context.
Thus GFP_ATOMIC is not necessary, and it can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.
