lib: sign conflict in sbi_tlb_entry_process()

Compiling sbi_tlb_entry_process() with GCC 11 and -Wextra yields:

lib/sbi/sbi_tlb.c: In function ‘sbi_tlb_process_count’:
lib/sbi/sbi_tlb.c:206:31:
error: comparison of integer expressions of different signedness:
‘u32’ {aka ‘unsigned int’} and ‘int’ [-Werror=sign-compare]
  206 |                 if (deq_count > count)
