[PATCH] crypto: caam/qi2 - use cpumask_var_t in dpaa2_dpseci_setup

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

Switch cpumask_t to cpumask_var_t as the former may be too big
for the stack:

  CC [M]  drivers/crypto/caam/caamalg_qi2.o
../drivers/crypto/caam/caamalg_qi2.c: In function ‘dpaa2_dpseci_setup’:
../drivers/crypto/caam/caamalg_qi2.c:5135:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
 5135 | }
