crypto: qat - increase size of buffers

Browse source 
[ Upstream commit 4e4e2ed22d ]

Increase the size of the buffers used for composing the names used for
the transport debugfs entries and the vector name to avoid a potential
truncation.

This resolves the following errors when compiling the driver with W=1
and KCFLAGS=-Werror on GCC 12.3.1:

    drivers/crypto/intel/qat/qat_common/adf_transport_debug.c: In function ‘adf_ring_debugfs_add’:
    drivers/crypto/intel/qat/qat_common/adf_transport_debug.c💯60: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
    drivers/crypto/intel/qat/qat_common/adf_isr.c: In function ‘adf_isr_resource_alloc’:
    drivers/crypto/intel/qat/qat_common/adf_isr.c:197:47: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size between 0 and 5 [-Werror=format-truncation=]
