lib: sbi: Don't check SBI error range for legacy console getchar

Browse source 
The legacy console getchar SBI call returns character value in
the sbiret.error field so the "SBI_SUCCESS < ret" check in
sbi_ecall_handler() results in unwanted error prints for the
legacy console getchar SBI call. Let's suppress these unwanted
error prints.

SBI error")
