[PATCH5b51a54ae2fa1cc8459b68a28b3c8ca7b7203994] PM / devfreq: mtk-cci: Fix variable deferencing before NULL check

[Sukrut Bellary]

smatch warning:
drivers/devfreq/mtk-cci-devfreq.c:135 mtk_ccifreq_target()
warn: variable dereferenced before check 'drv' (see line 130)

This is based on static analysis only. Compilation tested.
