[PATCH 1/1] lib: sbi: fix sbi_domain_get_assigned_hartmask()

[Heinrich Schuchardt]

'1' is a 32 bit integer. When shifting it by more than 31 bits it becomes
zero and we get an incorrect return value.

Addresses-Coverity-ID: 1568356 Bad bit shift operation
Fixes: 296e70d69da7 ("lib: sbi: Extend sbi_hartmask to support both hartid and hartindex")
