[PATCH] staging/erofs: fix sparse's warnings on undeclared symbols in erofs

[Bo YU]

From: Bo Yu <tsu.yubo at gmail.com>

Fix sparse warnings:

drivers/staging/erofs/utils.c:134:6: warning: symbol
'erofs_try_to_release_workgroup' was not declared. Should it be static?

Fixes: 51232df5e4b26("staging: erofs: fix race when the managed cache is enabled")
