crypto: xilinx - Remove set but not used variable 'drv_ctx' 

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/crypto/xilinx/zynqmp-aes-gcm.c: In function 'zynqmp_aes_aead_cipher':
drivers/crypto/xilinx/zynqmp-aes-gcm.c:83:30: warning:
 variable 'drv_ctx' set but not used [-Wunused-but-set-variable]

commit bc86f9c546 ("firmware: xilinx: Remove eemi ops for aes engine") left
behind this, remove it.
