[PATCH v2 1/5] sha1_file cleanup: remove redundant variable check

From: Hui Wang <redacted>

This variable check is always true, so it is redundant and need to be
removed.

We can't remove the init value for this variable, since removing
it will introduce building warning:
'base_len' may be used uninitialized in this function.
