ea5abd1f5e lib: sbi: Remove redundant call to sbi_hart_expected_trap_addr()
The variable "sbi_hart_expected_trap" has already been extern variable.
Therefore, the program can directly refer to it instead of calling
sbi_hart_expected_trap_addr().

instructions using Zalrsc when OpenSBI is compiled without Zaamo.
