[PATCH 1/1] Add FALLOC_FL_ALLOCATE_RANGE to the set of supported fallocate mode flags. This change improves code clarity and maintains by explicitly showing this flag in the supported flags mask.

[chuguangqing <chuguangqing@inspur.com>]

Note that since FALLOC_FL_ALLOCATE_RANGE is defined as 0x00, this addition
has no functional modifications.
