scsi: ufshcd-crypto-qti.c: do not resume for key reprogram

Browse source 
When reprogram_all_keys is called from keyslot manager, it is
done as part of the ufs resume context. This will cause a hang
when keyslot program tries to do a resume again. Avoid doing a
resume if keyslot program is called from resume context.
